Question

For the following set of data, please compute the following:

a. Mean

b. Median

c. Skew (Left, Right, or None)

d. Mode

e. Range

f. Variance

g. Standard deviation.

Y = {3, 7, 5, 6, 9, 14, 2, 1, 6}

Answer 1

Solution-

a. Mean

b. Median & d. Mode

c. Skew (Left, Right, or None)

Where,

Mean, Median and Mode are approximately same. So, the data is None skewness.

means data is symmetric.

d. Mode

The Mode is 6

e. Range

Range = Maximum - Minimum

= 14 - 1 =13

Range = 13

f. Variance

g. Standard deviation.
