Question

The values and relative frequencies for a set of data are shown below. Complete the cumulative relative frequency table. Provide your answer below: Data Value Relative Frequency Cumulative Relative Frequency 1 0.22 2 0.19 3 0.36 4 0.23

Answer 1

The cumulative relative frequency for each data value are ; 0.22, 0.41, 0.77 and 1.00

How to complete the cumulative relative frequency table

To complete the cumulative relative frequency table, calculate the cumulative relative frequencies by adding up the relative frequencies for each data value and all the previous values.

Find the completed cumulative relative frequency table in the attached image.

1. Relative Frequency= 0.22 Cumulative Relative Frequency= 0.22

2 Relative Frequency= 0.19 Cumulative Relative Frequency = 0.19 + 0.22 =0.41

3 Relative Frequency = 0.36 Cumulative Relative Frequency = 0.36 + 0.41 = 0.77

4 Relative Frequency = 0.23 Cumulative Relative Frequency = 0.23 + 0.77 = 1.00

The cumulative relative frequency for each data value is obtained by adding the relative frequency of that value to the cumulative relative frequency of the previous value(s).
