Cumulative Frequency

What is cumulative frequency?

Cumulative frequency is the running total of frequencies in a dataset, showing the number of data points that fall below or at a specific value. It is a key concept in statistics, used to summarize data, especially when visualizing distributions. Cumulative frequency is often represented in tables or graphs, where each value includes the total count of all previous observations, making it easier to analyze patterns, trends, and distributions within a dataset.

Why does cumulative frequency matter?

Cumulative frequency is a powerful tool for summarizing and visualizing data, particularly in clinical research. It helps to better understand distributions, track trends, and identify patterns in patient characteristics, treatment outcomes, and adverse events. By using cumulative frequency, researchers can gain valuable insights that inform decision-making and improve the quality of clinical studies.
