False Simple random sampling is a method associated with a high degree of generalizability A. True B. False A nominal scale is always dichotomous A. True B. False With face validity, the validity is not tested statistically A. True B. False Army rank (such as soldier, corporal, sergeant, lieutenant etcetera) is a variable with an ordinal scale A. True B. False The difference between an ordinal and ratio scale is that the ordinal scale has an absolute zero point A. True B. False With systematic sampling one divides the population into subgroups and chooses the test subject randomly from a number of randomly chosen subgroups A. True B. False Stratified sampling and cluster sampling are examples of probability sampling A. True B. False Stability and consistency are both indicators of the reliability of a measure A. True B. False What is the measurement level of income, measured in the following way: "What is your annual gross income?\" < 15.000 20.000 - 30.000 30.000 - 45.000 > 45.000 A. Nominal B. Ordinal C. Interval D. Ratio Which of the following alternatives is not an example of a ranking scale A. Pair comparison B. Forced choice C. Likert scale D. Comparative scale About a scale (set of questions) it can be said that the indicates_________ how well the measure taps the concept as theorized. Which word or words is/are missing? A. Content validity B. Construct validity C. Criterion-related validity D. Stability Which of the following alternatives is not an example of a rating scale? Paired comparison Likert scale Semantic differential scale Stapel scale Concurrent validity is a form of construct validity A. True B. False A characteristic of a variable on interval level is that it has an absolute zero point A. True B. False Construct validity ensures that the measure includes an adequate and representative set of item A. True B. False In probability sampling all elements of a population have a known and nonzero chance of being included in the sample A. True B. False If all the elements in the population are seen as equal and every element has an equal chance of being chosen, we speak of: A. Simple random sampling B. Systematic sampling C. Stratified random sampling D. Cluster sampling The following question "Indicate the order in which you prefer the following coke-labels. Give the favourite label a 1, the label you prefer next a 2, and so on: Coca Cola _____, Pepsi ______, Dr Peper _____ " is an example of: A. A rating scale B. An itemized rating scale C. A ranking scale D. None of the above answers is correct Which of the following sampling designs is a form of non-probability sampling? A. Systematic sampling B. Area sampling C. Quota sampling D. Cluster sampling In what way do the concepts of causality and correlation relate to each other? A. Causality is needed for correlation B. Causality is one of the conditions for correlation C. Correlation is one of the conditions for causality D. Correlation alone is enough evidence for causality Which test could be best used to test the hypothesis that the average grade of a group or population of students is higher than a 7 on a 10-points scale? A. An independent sample t-test B. One sample test C. Paired sample t-test D.
