21 A researcher records the preferred research method of 200 students as survey, interview, observation, or experiment. Which type of classification is most appropriate?

22 A table presents the number of employees in different age groups, but the group intervals 20–29 and 29–39 overlap at age 29. What is the main problem with this table?

23 A researcher wants to compare the number of books read by students in four departments during one semester. Which graph is most suitable?

24 Which feature is essential when constructing a frequency distribution for continuous data?

25 A pie chart shows that a category represents 25% of the observations. What angle should be used for that category?

26 A histogram is preferred over a bar graph when the researcher is presenting which type of variable?

27 In a table, the frequencies for five categories are 12, 18, 25, 30, and 15. What is the percentage frequency of the third category?

28 A researcher uses a line graph to show monthly research expenses. What does a steep upward segment generally indicate?

29 Which table component helps readers understand the meaning of abbreviations or special symbols used in the table?

30 A scatter diagram shows points clustered closely around an upward-sloping line. What relationship does this most likely suggest?

31 Which section of a research report normally explains the research problem, objectives, and significance of the study?

32 A report describes the sampling procedure, data collection instrument, and statistical techniques used. In which section should this information appear?

33 What is the primary purpose of an abstract in a research report?

34 A researcher finds that the observed results support the first hypothesis but not the second. Where should the interpretation of this difference mainly be presented?

35 Which practice best improves the organization of a lengthy research report?

36 A researcher includes a lengthy questionnaire that would interrupt the flow of the main report. Where should it normally be placed?

37 Which statement best distinguishes the results section from the discussion section?

38 A conclusion in a research report should primarily:

39 Which use of artificial intelligence can most directly assist a researcher during an initial literature search?

40 A researcher uses an AI tool to summarize several articles. What is the most important quality-control step?

41 A researcher records respondents' employment status as employed, unemployed, self-employed, and retired. Which classification principle is most important when assigning each respondent to one category?

42 A continuous variable has observations ranging from 12 to 97. If seven equal-width, non-overlapping classes are required and all values must be included, which class width is most defensible?

43 A grouped frequency table uses the classes 10-19, 20-29, and 30-39 for a continuous measurement recorded to the nearest whole unit. Which adjustment is required before constructing a histogram?

44 Two departments report employee satisfaction using different sample sizes. Which display best supports a valid comparison of their satisfaction distributions?

45 A time series shows monthly sales, but January has twice as many operating days as February. Which presentation most directly reduces the risk of a misleading comparison?

46 A researcher wants to show the relationship between household income and annual medical expenditure, including possible outliers. Which graph is most appropriate?

47 A bar chart begins its vertical axis at 95 rather than zero, making a small difference appear very large. What is the principal methodological problem?

48 A table reports treatment outcome by sex, but the sex categories include a substantial number of missing responses. Which addition most improves interpretability?

49 A frequency distribution has unequal class widths. Which graphical rule is necessary for a histogram to represent the distribution accurately?

50 A report's results section contains statistically significant findings, while its discussion section explains their implications and compares them with prior studies. Which arrangement follows sound reporting practice?

51 A study has a statistically significant association between two variables, but the design is cross-sectional and potential confounders were not controlled. How should the conclusion be worded?

52 A report's abstract states that an intervention was effective, but the body reports a confidence interval that includes no effect. What is the most appropriate revision?

53 Which sequence best represents a conventional empirical research report?

54 A limitation is identified only after the results are interpreted, and it substantially affects external validity. Where should it be addressed most explicitly?

55 A report includes a large technical table that is necessary for reproducibility but interrupts the main argument. Where should it usually be placed?

56 A researcher changes the order of several paragraphs in a draft report but leaves all citations attached to their original claims. What verification is most important before submission?

57 An AI tool generates several apparently relevant references for a literature review, but some cannot be located in scholarly databases. What is the most appropriate action?

58 A researcher uses an AI system to summarize confidential interview transcripts. Which safeguard is most essential before uploading the data?
