Question

# of courses | Frequency | Relative frequency | cumlative frequancy |

1 | 20 | 0.4 | |

2 | 15 | ||

3 |

What/ how do I fill in the blanks?

Step 1

Relative frequency can be calculated by dividing the individual frequency in an interval by total number of data values. As relative frequency for first interval is given along with individual frequency, total number of data values can be calculated as shown below.

Step 2

Total number of data values have been calculated as 50.

We know that Sum of frequencies = Total number of data values

Therefore, last value under Frequency column can be calculated as 50 -(20+15) = 15
