Relative Frequency in Tables
relative frequency
Frequency tables often include a column for the relative frequency, which represents the proportion of observations that are in a particular category and can be expressed as a decimal or a percentage.
To find the relative frequency, divide the frequency of the outcome you’re interested in by the total number of outcomes in the sample.
[latex]\text{relative frequency} = \frac{\text{subgroup}}{\text{total}}[/latex]
Converting between fractions, decimals, and percentages:
Proportion [latex]= \dfrac{\text{part}}{\text{whole}}[/latex]
- To write a fraction as a decimal, divide the numerator by the denominator.
- To convert a decimal to a percentage, move the decimal point two places to the right and insert a percent symbol, [latex]\%[/latex], after the number.
