Question

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

Explanation / Answer

6) variance could be used to determine the variability for a nominal scale

variance used to measures how far a set of numbers are spread out from their average value.

Option D ) is correct.

7 ) Interquartile range typically gets larger as sample size increases.

IQR measured the variablity based on dividing the data into quartiles.

Option A) IQR is correct

Q 8) Range is nothing but difference between larger and smaller observation.

Option B ) Range is correct

Q9) variance is equals to square root of standard deviation.

Option D ) Variance is correct

Q10) Range is represents the crudest, or least sophisticated, measure of dispersion.

Because if the data contains an outliers then range may be affected by it.

Option B ) Range is correct
