TRUE/FALSE

1. Empirical research is first a mathematical rather than a logical operation.

ANS: F REF: 274

2. When reporting marginals for univariate analysis, the presentation must be in raw numbers and cannot be reported in percentages.

ANS: F REF: 275

3. In univariate analysis, missing data can be reported in several different ways.

ANS: T REF: 275-276

4. Summary averages or measures of central tendency include the mode, mean, and range.

ANS: F REF: 276

5. The range is a measure of central tendency.

ANS: F REF: 276

6. Because extremes in a distribution (a very large or very small number) can impact the mean, it is usually important to examine measures of dispersion about the mean.

ANS: T REF: 278

7. Univariate analysis and subgroup comparisons focus on describing variables while bivariate analysis focuses upon people.

ANS: F REF: 284

8. Bivariate analyses typically have an explanatory purpose.

ANS: T REF: 284

9. Tests of statistical significance should not be calculated on relationships observed in data collected from whole populations.

ANS: T REF: 292

10. When we generalize from samples to larger populations, we use inferential statistics to test the significance of an observed relationship.

ANS: T REF: 291-292
