What is the difference between frequency and relative frequency?

Back

Frequency refers to the count of occurrences of a specific outcome, while relative frequency is the proportion of that outcome compared to the total number of observations.

What is an example of a categorical variable?

Back

An example of a categorical variable is 'favorite color,' which can take on values like red, blue, green, etc.

What does it mean if a two-way frequency table shows a high frequency in one category?

Back

A high frequency in one category indicates that many observations fall into that category, suggesting a strong preference or trend.
