Explanation / Answer

Solution:

a) Given histogram data is unimodal and positively skewed.

b) Measure of center is Median, it is more appropriate for data.

Reason : When the data is skewed, the median is more appropriate to use as the measure of a center.

c) Measure of spread for this data is IQR.

Reason: If a data has skewness,IQR is used as a measure of spread.
