Specificity Needed: "Many Studies" Isn't Good Enough for Your Committee

Found in 2-4% of dissertation sentences. Every time you write "many," "significant," or "various," your committee reads "I didn't actually count."

FIX

Replace the vague quantifier with specific details or citations.

What This Issue Is

"Many studies have shown..." How many? Three? Thirty? Three hundred? "The intervention had a significant impact..." Significant how? Statistically significant at p < .05? Practically significant in terms of effect size? Or do you just mean "big"? In academic writing, these vague quantifiers are placeholders for precision you haven't yet achieved.

Your committee reads vague language as one of two things: either you don't know the specifics (which raises questions about the depth of your reading), or you know them but can't be bothered to include them (which raises questions about your scholarly rigor). Neither interpretation works in your favor.

The fix is almost always available in your sources. If you wrote "many studies," you can count them or cite a meta-analysis that counted them. If you wrote "significant impact," you can report the actual effect size or statistical result. If you wrote "various factors," you can name the factors. Precision doesn't make your writing longer—it makes it credible.

Why Your Committee Flags It

Terms like "various factors" or "many studies" promise breadth without delivering it.

Before & After Examples

Before

Various factors contribute to student success.

After

Three primary factors contribute to student success: parental involvement, teacher quality, and socioeconomic status (Garcia, 2021).

"Many researchers" replaced with specific count and actual citations.

Before

Many researchers have studied the effects of poverty on education.

After

The relationship between poverty and educational outcomes has been extensively documented, with three major meta-analyses published since 2015 (Berkowitz et al., 2017; Dietrichson et al., 2017; Morgan et al., 2019).

"Significant impact" replaced with actual effect size and statistical significance.

Before

The program had a significant impact on student achievement.

After

The program improved student achievement by an average of 0.4 standard deviations on standardized math assessments (d = 0.42, p < .01; Thompson, 2021).

"Various factors" replaced with the actual factors named in the source.

Before

Various factors contribute to teacher burnout.

After

Teacher burnout is driven by three primary factors: workload intensity, lack of administrative support, and emotional labor (Skaalvik & Skaalvik, 2017).

Frequently Asked Questions

Specific enough that a reader can verify your claims. "Many studies" is unverifiable. "Three meta-analyses conducted between 2015 and 2020" is verifiable. "Significant impact" is meaningless. "A 15-percentage-point increase in graduation rates" is meaningful. The standard isn't perfection—it's precision that demonstrates you've actually engaged with the evidence.
Rarely, and only when the exact count genuinely doesn't matter to your argument. "Several interview participants mentioned time constraints" is acceptable in a methodology section where you'll provide exact counts in your findings. "Several studies support this claim" in a literature review is not acceptable—name the studies.
In everyday language, "significant" means "important" or "notable." In statistical language, it means the result is unlikely due to chance (typically p < .05). In a dissertation, using "significant" without specifying which meaning you intend creates confusion. Use "statistically significant" for statistical results and "substantial," "meaningful," or "notable" for practical importance.
You're likely using summary language where your committee wants evidence language. Every time you make a claim about quantity ("many"), degree ("significant"), or scope ("various"), you need to back it up with the actual number, the actual measure, or the actual list. Think of it this way: if someone asked "how many?" or "like what?" after reading your sentence, you need to add that information.
