Frequency refers to how often an observation occurs relative to the total number of observations.
This is calculated by dividing the frequency by the total number of observations, resulting in a fraction or decimal.
If you want the result as a percentage, move the decimal point two places to the right and add a "%" sign. Frequency can be expressed as a percentage, fraction, or decimal—it's your choice! For example, 10%, 0.10, and 1/10 represent the same value in different formats.
