A frequency distribution is a way to organize data by showing how often each value or range of values occurs in a dataset. It helps to summarize large amounts of information, making it easier to see patterns and trends. For example, if you have test scores from a class, a frequency distribution can show how many students scored within specific ranges, like 0-10, 11-20, and so on. This method is commonly represented in tables or graphs, such as histograms. By visualizing the data, you can quickly identify the most common scores, outliers, and overall distribution, aiding in analysis and decision-making.
