Study Notes
Frequency Distribution
- A frequency distribution is a tabular summary of data that displays the frequency (or number) of items in each of several non-overlapping classes.
- The purpose of a frequency distribution is to provide insights about the data that cannot be quickly obtained by looking only at the original data.
Types of Frequency Distributions
- Relative frequency distribution: a tabular summary of a set of data showing the relative frequency for each class, which is a proportion of the total data items.
- Percent frequency distribution: a tabular summary of a set of data showing the percent frequency for each class, calculated by multiplying the relative frequency by 100.
