Question

The scores on a recent statistics test are given in the frequency distribution below. Construct the corresponding relative frequency distribution. Round relative frequencies to the nearest hundredth of a percent if necessary.

Answer 1

The relative frequency distribution is 0-60 (6.45%).

Explanation:

A relative frequency is calculated by the fraction or proportion of number of times the occurrence of a value. The fraction of each frequency to the total number of data points in the sample expresses the relative frequencies. Relative frequencies can be written in the form of fractions, percent or decimals.

The frequency distribution table shows how often the event happens. The following are different types of frequency distribution:

i) Grouped frequency distribution

ii) Ungrouped frequency distribution

iii) Cumulative frequency distribution

iv) Relative frequency distribution

v) Relative cumulative frequency distribution
