Question

1. What is the relative frequency value for "Fish"? Rel. Freq PET Type Dog Cat Fish Other Totals Count 16 28 8 4 56

Answer 1

The relative frequency is equal to the absolute frequency of that class or category divided y the sample size.

In this case, the absolute frequemcy of "fish" is 8 and the sample size (the total count) is 56.

Then, the relative frequency is:

`f=(F)/(N)=(8)/(56)=(1)/(7)\approx0.143`

The relative frequency of fish is 1/7 (approximately 0.143).
