Question

The ___ is the easiest measure of dispersion to calculate .
(a) Range
(b) mean alsolute deviation
(c) standard deviation
(d) variance​

Answer 1

The range is the easiest measure of dispersion to calculate.

• The range is the difference between the largest and smallest value of the data in the given set.

• Example: Let the data set be 2, 4, 7,1, 8, 9. From the data, the smallest value is 1 and the largest value is 9.
• The range from the above example = (9-1) = 8.

• The range is the most simple and easy way to calculate the measure of dispersion.

Answer 2

The A. Range is the easiest measure of dispersion to calculate.

Definition of Range:

• The range is the difference between the largest number and the smallest number of a given data.
• The range is the easiest measure of dispersion to calculate.

Reasons supporting Answer:

• Option B. Mean absolute deviation is the average distance between each point and the mean in a given data. This tool is useful in assessing the variability in a given data.
• Option C. Standard deviation is used to measure the amount of variation of a set of values in a dataset.
• Option D. Variance is the measure of variability from the average or the mean value of the dataset.

Hence, Option A. Range is the easiest measure of dispersion as it involves direct calculation from the given data set.
