Question

Lia and Elise are discussing measures of spread. Elise says the best measure of spread with which to compare data sets is the IQR. Lia says the best measure of spread with which to compare data sets is the standard deviation. Elise is correct if both data sets are:
a) large
b) normal
c) skewed
d) small

Answer 1

The correct answer is normal.

Step-by-step explanation:

• IQR stands for Interquartile range.

• This is used in descriptive statistics.

• In other words, this is also called mid spread.

• To find this range, one has to arrange the numbers from lower values to higher.

• This measures variability of data sets.
