Challenge yourself with these true/false questions. Click on your choice to see if you are correct.

  1. Magnitude refers to an inherent order of value from smaller to larger. (True/False)

  2. The abstract number system has no specific or well-defined rules. (True/False)

  3. A nominal scale is essentially a naming scale. (True/False)

  4. To measure a variable is to assign numbers that represent values of the variable. (True/False)

  5. The term data refers to the methods used to make observations. (True/False)

  6. When assigning numbers to a variable, the researcher works with five sets of numbers. (True/False)

  7. As a measure, class rank will have the properties of identity, magnitude, and equal intervals, but no true zero. (True/False)

  8. Temperature measured on the Fahrenheit scale has a true zero point. (True/False)

  9. Interval scales of measurement provide a closer match to the abstract number system than ordinal scales of measurement. (True/False)

  10. A ratio scale of measurement has all of the properties of the abstract number system including identity, magnitude, equal intervals, and a true zero. (True/False)

  11. Only ratio scales of measurement produce score data. (True/False)

  12. Measurement error can only occur with ordered or score data. (True/False)

  13. A social-desirability response set tends to reduce measurement errors. (True/False)

  14. The way in which the researcher operationally defines a variable will affect the typical measurement error for that variable. (True/False)

  15. The operational definition of a variable defines for the researcher how that variable will be measured and/or manipulated in the study. (True/False)

  16. Internal consistency reliability is a measure of how closely two raters agree. (True/False)

  17. A measure must be reliable in order for the measure to be valid. (True/False)

  18. If test-retest reliability is not high, the operational definition of the variable must be inadequate. (True/False)

  19. Validity refers to how consistently the measure produces the same score for a given individual. (True/False)

  20. Scale attenuation effects will occur whenever an ability measure is too easy or too hard for the population under study. (True/False)

  21. A floor effect occurs if a test is too easy. (True/False)

  22. Science rests on the accuracy of the subjective judgment of scientists. (True/False)

  23. Falsifying data is an example of serious misconduct in science. (True/False)
