Question

The _____________ is the most important descriptive statistic for a categorical variable. It is calculated by dividing the number of observations in the category of interest by n, the total number of observations in all categories combined.

Answer 1

Proportion

Explanation:

Proportion is just the division of the data that meets the description, between the total number of data present in the study.

For example, let's suppose that we have a tiger, a lion, a sheep, a cow and a horse, and we want to know the proportion of animals that eat meat, then, only 2 out of 5 of those eat meat, the tiger and the lion, meaning
`(2)/(5)`, which would be the proportion, or 0.40
