GMAT Information and Ideas : (Ideas) Questions
Research conducted by Dr. Patricia Chen and her team examining publications in the Journal of Applied Psychology from 2015 through 2020 demonstrates a troubling deterioration in research methodology standards over this period: publications from 2015 maintained an average of 850 study participants with 89% utilizing appropriate control groups, while by 2020, publications averaged merely 340 participants with only 67% implementing sufficient controls, resulting in significant statistical power deficiencies that reviewers routinely identified. Given the journal's established policy mandating minimum statistical requirements for publication approval, Chen and colleagues hypothesize that a credibility crisis developed circa 2020, which was presumably resolved—notwithstanding the journal's ongoing budgetary limitations constraining review resources—when incoming editor-in-chief Dr. Martinez chose to ______
Which choice most logically completes the text?
preserve existing sample size requirements while enforcing more rigorous control group criteria that could be assessed through current review protocols.
elevate the minimum sample size threshold beyond the levels mandated in 2015.
mandate larger sample sizes while preserving the control group criteria utilized in 2020 publications.
create funding to assist researchers lacking adequate training in control group methodologies.

Part B: Core Understanding
Main Point: Research shows the Journal of Applied Psychology experienced declining methodology standards from 2015-2020, creating a credibility crisis that was resolved when editor Martinez took action within budgetary constraints.
Key Problem: Both sample sizes (850 to 340) and control group usage (89% to 67%) declined significantly, creating statistical power issues.
Step 2: Interpret the Question Precisely
This is a fill-in-the-blank question asking us to choose the best logical connector. The answer must create the right relationship between what comes before and after the blank.
Step 3: Prethink the Answer
- The correct answer must address the specific problems: declining sample sizes and fewer proper control groups
- However, it must work within budgetary limitations that constrain review resources
- The solution should target the most serious issue that can be fixed without dramatically increasing review burden
preserve existing sample size requirements while enforcing more rigorous control group criteria that could be assessed through current review protocols.
- Addresses control group problem while working within existing review constraints
- This improves standards without adding review burden
elevate the minimum sample size threshold beyond the levels mandated in 2015.
- Would require more extensive review of larger studies
- Contradicting the budgetary limitations
mandate larger sample sizes while preserving the control group criteria utilized in 2020 publications.
- Preserves the problematic 2020 control group criteria
- Not actually solving the credibility crisis
create funding to assist researchers lacking adequate training in control group methodologies.
- Creating funding contradicts the ongoing budgetary limitations mentioned in the passage
