Here is a list of errors of grammar and style which I have found to be fairly common in theses
and dissertations. Now that you know they are errors, don't make them. I have provided references to sections of the
7th(PM7), 6th (PM6), and/or 5th edition of the APA Publication Manual (PM5) where appropriate.
"Affect" and "Effect"
Get out your dictionary. Used as a noun "affect" means "emotion." Used as a verb "affect" means "to act upon." Used as a noun "effect" means "a result or consequence." Used as a verb "effect" means "to bring about or cause to happen." Examples: "What is the effect of this drug? Does it affect cognition? Does it alter affect? Could we use it to effect a change in one's personality?"
Alphabetical Order of Citations Within Parentheses
When listing several citations within parentheses, do so alphabetically, not chronologically. For example: "Cannibalism has been studied by several psychologists (Carr, 1981; Maslow, 1936; Wuensch, 1990)." OWL
Amount, Quantity, Number-- see this guide.
Use the ampersand to stand for "and" within parentheses, but not outside parentheses. For example, say "Wuensch and Urwalt (1996) reported that estrogen's effects in tropical climates differed from its effects in temperate climates," but say "Several others have reported similar interactions (Mueller, 1995; Wuensch & Urwalt, 1996; Xenos, 1982)." OWL
ANOVA Independent Variables ("Factors")
Don't refer to them as "factors," reserve that term for the weighted linear combinations of variables resulting from a factor analysis (PM6, 4.20). Do not capitalize the names of variables unless they are connected by "x" -- for example, say "the main effects of sex and dose fell short of statistical significance, but the Sex x Dose interaction was significant."
Do not attribute human characteristics to <nonhuman> animals or to inanimate sources. (PM7, 4.11). This was one of Kathleen Row's pet peeves. She wrote "Beware of attributing human-like attributes to theories, hypotheses, or psychological concepts. For examples, theories do not think, feel, or have relationships." As another example, "The current investigation will gather and analyze information ...." No, the investigator will gather and analyze the information. Another example: "These simulated data looked at mean pulse increases in four different groups ..." Also read this and this.
Students frequently insert blank spaces where they do not belong. The best way to prevent this to is turn the Show/Hide formatting marks ON. Blank spaces will then appear as dots, and you can see the ones that should not be there. One of the places that students most often put such blank spaces is at the end of the last sentence in a paragraph. Usually this has no ill effect, but it can have an adverse effect on formatting if you switch from one computer to another or one printer to another. On a related topic, be consistent with respect to how many blank spaces you will put between each sentence and the next. Previous editions of the APA Publication Manual clearly stated (PM6, 4.01) that there should be TWO blank spaces between sentences, but the seventh edition now specifies one space.
In a thesis at ECU, set all headings in bold font (and some of them in bold italic font). See my Thesis Tips page for more details (to which you can link at the bottom of this document). Also see this document: APA Style Headings
Read the APA Publication Manual carefully regarding appropriate use of upper case. Students tend to capitalize things they shouldn't, such as the names of variables (but see the comments above about ANOVA independent variables). (PM6, 4.14 through 4.20)
The word "factor" should be capitalized when it is followed by a number -- for example, "The first factor captured 46% of .... As shown in Table 3, Factor 1 loaded well on ...." You should also capitalize the names that you give to derived factors -- for example, "The Chinese participants scored much higher on Temporal Farsightedness (Factor 5) than did ...."
Last names which start with a lowercase letter.
Citations, Repeated Within Same Paragraph
Within a paragraph, if the author's name appears in narrative (not within parentheses), you do not give the year in any subsequent narrative citations. The year is always given for parenthetical citations. (PM6, 6.11)Conjunctions as the First Word in a Sentence
Do not start a sentence with a conjunction. And don't end one with a preposition. See Rules for Writers. Then see another opinion.Commas and Quotation Marks
Put the closing comma (or period or any punctuation mark that was part of the quoted material) within the quotation marks. (PM6, 4.08)
Criticizing the Author of This Document for Putting Two Spaces After Periods
Nobody likes a pompous arse. Reading is facilitated by using two spaces, and this is not an APA manuscript.
Treat this word as a plural noun. The singular is "datum." Quoting from the PM, "Correct: The data indicate. Incorrect: The data indicates. (PM7, 6.11)
DF for F
Put a blank space after the comma which separates the numerator df from the denominator df. (PM6, 4.44.)
Direction of Effect
Do not indicate a direction of effect when the results were not significant, unless you were testing directional hypotheses. Since we rarely ever test directional hypotheses, you should almost never indicate a direction of effect with nonsignificant results. Nonsignificant results mean that we do not know the direction of effect. For example, do not write "Men were not significantly less politically conservative than were women" unless your alternative hypothesis was that men would be less conservative than women. Do write "Sex did not significantly affect political conservatism." Do, however, always indicate the direction of effect with significant results.
Equality and Inequality Signs
Put a blank space on each side of them. (PM6, 4.44). From the 7th edition (6.45) of the pub manual: “Space mathematical copy as you would space words: a+b=c is as difficult to read as wordswithoutspacing. Instead, type a + b = c.
It is perfectly acceptable for a research hypothesis to be a range null hypothesis -- that is, that the correlation between two things or sets of things is very close to zero. This should not be stated in terms of whether or not the tested correlation will be statistically significant in the obtained sample (which is largely a matter of how large the sample will be). For example, Mike wrote "Openness to Experience will not be significantly correlated with cyberloafing." Statistical/research hypotheses are statements about the value of a population parameter, usually that the rho between two things has a value other than zero. “Significant” refers to the value of p, that is, whether or not the data are highly unlikely given the hypothesis. Accordingly, the word “significant” has no place in a research hypothesis. If you want to predict that the correlation between two things is very small or zero, do so, specifying what very small or zero means – for example, -.1 < rho < +.1. Then conduct an equivalence test. For Mike, an appropriate research hypothesis would be "The association between Openness to Experience and cyberloafing is very small, |rho| < .1.
There is no period after "et" (which is not an abbreviation), there is one after "al." 8.17. If there are two authors, cite both names. If there are three or more, use “et al.,” unless that would create ambiguity. For example, “Wuensch, James, Wundt, & Fechner, 2019” and “Wuensch, Münsterberg, Capretta, & Spence, 2019” would both reduce to “Wuensch et al., 2019.” To avoid such ambiguity, you would write Wuensch, James, et al., 2019” and “Wuensch, Münsterberg, et al., 2019). If only the last author differs, do not use “et al,” do list all authors’ names. For example, “Wuensch, Münsterberg, Capretta, & Cattell, 2019” would not be reduced to “Wuensch, Münsterberg, Capretta, et al., 2019,” because “et al.” means “and others,” not “and one other.”. Note that there is NOT a comma before "et al." unless more than one author's name is given. (PM7, 8.17) OWL"Fewer" versus "Less"
If you can count it, use "fewer" rather than "less." See this.
Figures and Tables
Final Manuscript vs Copy Manuscript
The thesis is a final manuscript, not a copy manuscript. Copy manuscripts are those that are submitted to editors for review and, with luck, publication. The staff of the journal turns them into nice looking, easy to read, final manuscripts. The thesis should already be a final manuscript when it goes to the thesis committee. (Chapter 6 of the PM5)
Use 12 point Times New Roman, or 11 point Arial if available. (PM7, 2.19)
Please see this document: APA Style Headings
When used as a conjunction, it should be preceded by a semicolon and followed by a comma. For example, "I was upset about running over that possum; however, the possum stew was very tasty." More details.
In some disciplines it is common practice to state hypotheses formally. Personally, I prefer statements that express simply, and less formally, the expectations of the researcher. When hypotheses are stated, it is almost always the research hypotheses that are stated, not the null hypotheses. The word "significant" should NEVER be used in a hypothesis. The usual sort of hypothesis is a statement about the value of some parameter, usually a correlation coefficient." "Significance" refers to whether or not the fit between the data and the null hypothesis was sufficiently poor to assert, with great confidence, the research hypothesis.
The first line in every paragraph should be indented. Failure to do so has become a surprisingly common error among my recent graduate students. (PM6, 8.03)
This term should be used only for experimentally manipulated variables. Categorical variables not manipulated should be referred to as "predictor variables," "classification variables," "grouping variables," or another appropriate term that does not imply experimental manipulation. Read this document.Impact
As a noun "impact" means "a striking together," "the force of a collision," or "the power to produce changes." Given that last meaning, it is appropriate to say "Sometimes early experience has a profound impact upon later species identity." As a verb "impact" means "to strike together." It does NOT mean to affect. If you say "he impacted my thinking" you are saying he hit your thinking. Think of an impacted wisdom tooth -- it is striking up against your other teeth. See also Impact This, Buddy!
Italics, not Underlining
The only acceptable reason to use underlining rather than italics is that you are using a typewriter rather than a word processor.
Its vs. It's
I have a hard time with this one. "Its" is the possessive, as in "the rat licked its fur." "It's" is a contraction of "it" and "is," as in "it's not a rat, it's a chinchilla." It was not always so -- see the Word Detective.
Best to reserve this phrase for scales whose item response options reflect degree of agreement with a statement. See Likert.
The usual advice is to "set your word processor to double space and then forget it." If you are using Microsoft Word, see "Double Spacing" in my document Word Tips for the Thesis Typist. Do not put a blank line between one paragraph and the next paragraph. Do single space the abstract.
The Graduate School prescribes one inch margins all around. Microsoft Word, however, will allow tables to extend into the margin and does not have the courtesy to tell you when that happens. You must be vigilant, keeping an eye out for intrusions of tables into margins. Every graduate school has its own stories about the administrative assistant whose job is to check the margins on incoming theses and dissertations, rejecting those that have allowed any text or image into the sacred margins. There is such an administrative assistant in the graduate school here at East Carolina University: be vigilant.
"N" or "n"
Upper case N should be used when referring to total sample size. Lower case n should be used when referring to the sample size for a subgroup.Numbers
Numbers nine or less that don't represent precise measurements should be spelled out, unless they are grouped for comparison with numbers greater than nine. Spell them out at the beginning of a sentence. See the APA Publication Manual for details, exceptions, and examples. (PM6, 4.31 through 4.38)
Why just say "p < .05" or "p > .05" when you can give an exact value such as "p = .032 ?" On the other hand, if the p is less than .001, just say "p < .001." It is not very useful to say something like "p = .000000283." Although p is an abbreviation, do not follow it with a period. See section 4.35 in the PM6 where it reads: "When reporting p values, report exact p values (e.g., p = .031) to two or three decimal points. However, report p values less than .001 as p < .001. The tradition of reporting p values in the form p < .10, p < .05, p < .01, and so forth, was appropriate in a time when only limited tables of critical values were available. However, in tables the 'p <' notation may be necessary for clarity." My advice: If p > .06, report it to two decimal points. If .001 < p < .06, report it to three decimal points. If p < .001, report "p < .001." Here is the relevant text from page 180 of the 7th edition:
To force a page break, in Word, just hold hold down the Ctrl key while you hit the Enter key. Do not insert multiple carriage returns (Enter) to force a new page.
Page numbers should not appear on the first page of each chapter. Prefatory pagination is really strange: Consult my Thesis Tips page.
Passive/Active Voice and the First Person
Use of the active voice with the first person is strongly encouraged. (PM6, 3.18.) Also, see Use of First Person in APA Style .
I just don't like the sound of this word, but even worse is that it is almost always misused. It does not mean "a lot." I means "too much."
Pronouns for Nonhuman Animals
Use neuter pronouns unless the animals have been named. (PM6 3.20.) I guess that I would use "he/she" for my pet earthworm, Squiggly. Squiggly is a hermaphrodite. APA probably considers "hermaphrodite" an insensitive term, but it describes earthworms accurately. I would still use a neuter pronoun when referring to a named animal from a species that does not reproduce sexually.
Prepositions at the End of a Sentence
Avoid them. "A preposition is a poor word to end a sentence with" can be changed to "A preposition is a poor word with which to end a sentence."
The redneck plural is using the singular possessive when the plural nominative or objective should have been used. An apostrophe should not be used when forming the plural of a noun unless it is possessive. For example, you should write "these possums make great stew," not "these possum's make great stew." The plural possessive would be "possums'," as in "this garbage dump is the possums' favorite place to forage."
When referring to the author of the thesis, use "I" or "my," not "we" or "our." See the PM6, 3.09, "Editorial we."
Avoid them, if possible. Don't tell me that Row and Boat (2004) reported that Stream (1996) found a quadratic relationship between misanthropy and family income, do go to the original source (Stream), read it, and then cite the original source. If you absolutely must use a secondary source (you have tried to get the original but could not), do it with proper APA style -- for example: "Rodin, Silberstein, and Striegel-Moore (1985, as cited in Striegel-Moore, Tucker, & Hsu, 1990) reported that ......."Sexist or Dehumanizing Language
Avoid sexist or dehumanizing language. Don't use "male" and "female" as nouns when referring to humans, acknowledge their humanity by referring to them as "men" and "women," or "boys" and "girls." Don't, however, use "man" and "woman" as adjectives. It is OK to use "male" and "female" as adjectives. (Item 3 in Table 2.1 in the PM6: "Use male and female as adjectives where appropriate and relevant (female experimenter, male participant). Males and females may be appropriate when the age range is quite broad or ambiguous. Avoid unparallel usage such as 10 men and 16 females.") Since "10 men and 16 females" dehumanizes women but not men, it is also sexist. See the APA Guidelines for Unbiased Language, especially Item 3 under gender and the following comment. See these examples of dehumanizing language.
APA used to discourage authors from using the term "subjects" to describe the research units when they were humans. They encouraged the use of words like "participants," "respondents," or some other terms less dehumanizing than "subjects." With the 6th edition of the publication manual, use of the word "subjects" has been designated as appropriate even when the subjects are humans. (PM6. 3.11, Guideline 3). What are "subjects?"Shifts of Tense
Shifting tenses back and forth annoys readers. Avoid it. (PM6, 3.06)
Use of the singular “they” is now encouraged. (PM7, 4.18)
Spacing After Punctuation Marks
Insert one space after commas, colons, and semicolons and periods that separate parts of a reference citation and periods in initials (for example, K. L. Wuensch). Do not insert a space after internal periods in abbreviations or around colons in a ratio. Space once after punctuation marks at the end of a sentence. (PM7, 6.1) To make it easier to see blank spaces, turn the Show/Hide formatting marks ON. Blank spaces will then appear as dots.
Call me old fashioned, but, unless needed to avoid ambiguity, I think one should avoid placing an adverb between "to" and the verbal. More than once I have been sent the following quotation as proof that I am a traditionalist:
Do not permit the negative sign (hyphen) to be split (at the end of a line) from the rest of the number. You can avoid this by using Word's nonbreaking hyphen -- see NonbreakingHyphen.jpg.
Set in italic font (or underline if you are using a typewriter rather than a word processor) statistical symbols such as t, F, and p. The PM6 (3.19) says not to set Greek letters in italics, even when used as statistical symbols, but I happen to think they look better when set in italics, so I do so in my handouts (I do follow the APA prescription in my manuscripts for journals that use APA style).
In Microsoft Word you can get Greek symbols, such as c , by clicking Insert, Symbol, selecting the font (use the Symbol font, it usually looks better than the others for Greek letters), selecting the symbol, and then clicking on insert, as illustrated here.Tense
Use the past tense to describe things that have already happened, such as the procedure you used to gather the data, the results you obtained when analyzing the data, and the writings of others. "Correct: "Sanchez (2000) presented similar results." Incorrect: "Sanchez (2000) presents similar results." " (PM6, 3.18)
Microsoft Word's tracking changes feature is a great tool to use when collaborating on a manuscript, including theses and dissertations. You must, however, be sure that you have accepted or discarded all tracked changes and deleted all comments from your manuscript before to convert it to pdf and deliver it to the graduate school. For example, you may have Word set to flag changed lines with a vertical line in the margin. If so, and there are still tracked changes in your Word document, that line will appear in the margin of the pdf document too, and the Graduate School will not like that. See Tracking Changes in Word .
Ideally, the members of your committee will use Track Changes to show what edits they recommend and to comment on your document. In the best scenario, the chair will work with the document you send and then send it on to the next member to add additional edits/comments, and so on, with the last member sending the document back to you and the chair. In this way, you need work with one document having all of the recommended edits and comments.
Be sure to preserve a record of the recommended edits and comments. If you make the recommended edits and then clear all comments and recommended changes and then send the document back, the members are likely to exclaim (WTF, how am I to know if she made the changes I recommended?" It you accept a recommend edit, leave a comment noting that you have done so (and identifying who requested that edit). If you decide not to accept a recommended change, leave a comment explaining why. Leave all comments by members remain in the document. Respond to them. The commenting member will clear the comment when e is satisfied that you have addressed it adequately.
All those using track changes should be sure that Office knows who they are. On university computers, by default, the author is "ITCS." That does not help one know from whom a particular comment came. See User Identity .
No, no, no. "Try to." See Try2.htm.
"Prefer the active voice. Preferred: "We conducted the survey in a controlled setting." Nonpreferred: "The survey was conducted in a controlled setting." The passive voice is acceptable in expository writing and when you want to focus on the object or recipient of the action rather than on the actor. For example, "The speakers were attached to either side of the chair" emphasizes the placement of speakers, not who placed them ......." (PM6, 3.18)
