11 In attitude measurement, scaling is commonly used to represent the:

12 Which scaling technique commonly uses response categories from "strongly disagree" to "strongly agree"?

16 Which scaling technique is based on cumulative statements arranged by increasing intensity?

17 Which scale of measurement classifies data into categories without any order?

18 Which measure of central tendency is always suitable for nominal data?

19 Which scale provides ordered categories but does not guarantee equal intervals between them?

20 Which scale has equal intervals and a true zero point?

21 A questionnaire produces nearly identical scores when administered to the same respondents two weeks apart, assuming their attitudes have not changed. Which quality is demonstrated?

22 A researcher asks several subject experts to determine whether a job-satisfaction questionnaire adequately covers pay, supervision, promotion, and working conditions. What is primarily being assessed?

23 Scores from a newly developed aptitude test are strongly associated with employees' job-performance ratings six months later. Which property does this evidence support?

24 Two observers independently classify the same classroom behaviors and agree on 92% of their classifications. Which measurement quality is most directly supported?

25 Before writing questionnaire items for "digital literacy," a researcher specifies observable abilities such as evaluating websites and using spreadsheets. Which development step is illustrated?

26 During a pilot study, almost every respondent selects the highest response category for one item. What is the most appropriate action?

27 A ten-item scale has a low Cronbach's alpha. Deleting Item 7 substantially increases alpha, and Item 7 has a negative item-total correlation. What should the researcher do first?

28 What is the main purpose of conducting a pilot test before administering a newly developed questionnaire to the full sample?

29 A researcher assigns respondents scores from 1 to 7 according to how favorable their attitudes are toward remote work. What does scaling accomplish in this case?

30 Which statement best distinguishes measurement from scaling in research?

31 A customer is classified as "dissatisfied," "neutral," or "satisfied." Which feature of scaling is present even though the categories have no stated numerical distance?

32 Why should a researcher define the direction of a scale before analyzing responses?

33 Respondents indicate agreement with each statement using categories from "strongly disagree" to "strongly agree," and item scores are summed. Which technique is used?

34 A brand is rated between bipolar adjective pairs such as "unreliable–reliable" and "traditional–modern." Which scaling technique is most appropriate?

35 A respondent allocates 100 points among price, quality, service, and convenience according to their relative importance. Which technique is being applied?

36 A political participation scale is designed so that agreeing with a difficult item implies agreement with all easier items below it. Which technique does this describe?

37 Employees are assigned department codes: 1 for Sales, 2 for Finance, and 3 for Operations. Which statistic is most appropriate for describing the most common department?

38 Contestants are ranked first, second, and third, but the performance gaps are unknown. Which summary measure is appropriate for these rankings?

39 Temperature measured in Celsius permits meaningful differences but not meaningful ratios. Why is the statement "C is twice as hot as C" invalid?

40 A researcher converts every weight from kilograms to grams using . Why are ratio comparisons preserved after this transformation?

41 A researcher measures classroom participation using a 12-item observation schedule. Two observers agree on 92% of ratings, but nearly all students are classified as "low participation." Which statistic is most appropriate for assessing agreement while correcting for chance?

42 A new anxiety inventory correlates strongly with an established anxiety scale but also correlates almost equally with a depression scale. Which conclusion is most defensible?

43 A knowledge test produces highly consistent scores across repeated administrations, yet experts find that it omits two major domains in the course specification. Which property is primarily deficient?

44 A researcher needs to measure a latent construct whose manifestations differ substantially across cultural groups. Which approach best supports sound cross-cultural measurement?

45 During scale development, an item has a corrected item-total correlation of , but experts judge it essential for covering a theoretically distinct facet. What is the best next action?

46 An exploratory factor analysis of 30 newly written items yields four correlated factors, although theory predicts one higher-order construct expressed through four dimensions. Which analytic strategy is most appropriate next?

47 In classical test theory, a 20-item scale has reliability . Assuming added items are parallel to the original items, approximately how many total items are required to reach reliability ?

48 A pilot scale has Cronbach's alpha of , but several items are nearly paraphrases of one another and the scale poorly predicts an external criterion. What is the most accurate interpretation?

49 Which statement best distinguishes measurement from scaling in social research?

50 Respondents rank five policies from most to least preferred. Why does this operation not, by itself, justify interpreting the difference between ranks 1 and 2 as equal to the difference between ranks 4 and 5?

51 A transformation changes every score according to . For which highest scale level does this transformation always preserve the scale's admissible meaning?

52 Researchers encode employment status as unemployed , part-time , and full-time . They then report that full-time status is "three times" unemployment status. What is the fundamental error?

53 Judges assign favorability values to attitude statements, and respondents later indicate only whether they agree with each statement. A respondent's attitude score is based on the scale values of endorsed items. Which technique is being used?

54 Four items are intended to form a perfect Guttman scale from easiest to hardest. A respondent endorses items 1, 2, and 4 but rejects item 3. How should this pattern be interpreted?

55 A researcher asks respondents to rate a university from to using a single adjective, "innovative," displayed above the numbers. Which technique is most directly represented?

56 A paired-comparison study contains 10 brands, and every unordered pair must be evaluated once. How many distinct comparisons are required?

57 Which analysis remains meaningful under every admissible strictly increasing transformation of ordinal data?

58 Temperatures measured in Celsius are converted to Fahrenheit. Which statement remains invariant under this transformation?

59 A ratio-scale variable is transformed to . Which quantity is guaranteed to remain numerically unchanged?

60 A researcher analyzes a single five-category Likert item with a highly skewed distribution and no defensible equal-interval assumption. Which summary is most consistent with its formal measurement level?
