What does relative frequency represent?

Back

Relative frequency represents the ratio of the frequency of a specific outcome to the total number of observations, often expressed as a percentage.

How do you calculate relative frequency?

Back

Relative frequency is calculated by dividing the frequency of a specific category by the total number of observations and multiplying by 100.

What is an example of a categorical variable?

Back

An example of a categorical variable is 'age group' (e.g., 18-25, 25-49, 50+).

Front

What does it mean if a certain age group has a higher relative frequency for a specific preference?

Back

It means that a larger proportion of that age group prefers that specific option compared to others.
