Question

1. This measure will give the most accurate assessment of the variability for a positively or negatively skewed distribution. Interquartile range Range Standard deviation Variance

2. This measure of dispersion can only be calculated and interpreted meaningfully with quantitative data. Interquartile range Range Standard deviation Variance

3. This value is calculated using only two numbers from the distribution of scores. Interquartile range Range Standard deviation Variance

4. This measure is closely related to the central tendency concept of the mean. Interquartile range Range Standard deviation Variance

5. The measure can only be used with ordinal scale of measurement or above. Interquartile range Range Standard deviation Variance

6. Some statisticians assert that this measure of dispersion could be used to determine the variability for a nominal scale (by counting the number of different categories or classifications). Interquartile range Range Standard deviation Variance

7. The value for this measure typically gets larger as sample size increases. Interquartile range Range Standard deviation Variance

8. This is found by examining how far apart the highest and lowest values in a data set are. Interquartile range Range Standard deviation Variance

9. The value of this measure is equal to the square root of another measure of dispersion. Interquartile range Range Standard deviation Variance

10. This represents the crudest, or least sophisticated, measure of dispersion. Interquartile range Range Standard deviation Variance

11. You have to be familiar with the concept of percentile and how to calculate them to make use of this measure of dispersion. Interquartile range Range Standard deviation Variance

12. This measure tells you how much the “typical” score deviates from the mean in a sample. Interquartile range Range Standard deviation Variance

13. The values of this measure would be slightly different depending on whether you were calculating this measure for a population or for a sample. Interquartile range Range Standard deviation Variance

14. The measure is calculated using information from all the observations in the sample. Interquartile range Range Standard deviation Variance

15. This measure of dispersion is most impacted by extreme scores in the data set. Interquartile range Range Standard deviation Variance

16. This measure has the clearest connection to measures of central tendency as well as inferential statistics. Interquartile range Range Standard deviation Variance

17. This is the most valuable measure of dispersion. Interquartile range Range Standard deviation Variance

18. This measure of dispersion is least immediately impacted by the presence of an outlier in the distribution. Interquartile range Range Standard deviation Variance

19. This measure of dispersion involves squared units of measure rather than the original unit of measure. Interquartile range Range Standard deviation Variance
