Chapter 2: Q. 4RP (page 88)

What is the relationship between a frequency or relative-frequency distribution of a quantitative data set and that of a qualitative data set?

Short Answer

Expert verified

The frequency distribution lists all possible values with their frequency.

The relative frequency distribution lists all possible values with their relative frequency.

For qualitative data, the classes are always the different single values that the variable can take on. For a quantitative data set it is possible that we need to use classes instead of single data.

Step by step solution
