1. A researcher wants to test if beer consumption differs between people dependent on the region of the country they live in. Region is measured as: East/West/North/South. On which scale is ‘region’ measured?
a. Independent scale b. Nominal scale c. Ordinal scale d. 4-points Likert scale
2. Suppose your teachers want to test if the average exam grade exceeds 6 significantly. Which test should we use?
a. Chi-square test b. T-test c. Regression analysis d. Not possible if you do not define explanatory variables.
3. What is untrue about an interval scale?
a. The distance between the intervals is constant b. Each interval is equal in size c. The scale has a logical null-point d. An interval scale is metric
4. Which statement about hypothesis testing is true?
a. The verbal hypothesis contains the same statement as the statistical null-hypothesis. b. The statistical null-hypothesis is rejected if the p-value is sufficiently low. c. If the statistical null-hypothesis cannot be rejected, this implies a confirmation of theoretical model d. Statistical and verbal hypotheses have no relation.
5. Consider the following reliability analysis for the variable customer differentiation. What could you conclude from it?
R E L I A B I L I T Y A N A L Y S I S - S C A L E (A L P H A)
