A frequency distribution is a summary of how often different values or ranges of values occur in a dataset. It organizes data into classes or intervals and shows the number of occurrences (frequency) of each value or interval.

For example, if you have a list of test scores, you might create a frequency distribution that shows how many students scored within specific ranges (e.g., 0-10, 11-20, etc.). This helps to visualize patterns in the data, making it easier to see which scores are most common.

Frequency distributions can be represented in various forms, including tables, histograms, or bar charts, providing a clear overview of the data distribution.
