How do you find cumulative frequency? And how do you describe the shape, spread, and center of a distribution? That's what we're going to find out today! Here we will learn cumulative frequency. The cumulative frequency of a value of a variable is the number of values in the collection of data less than or equal to the value of the variable. For example: Let the raw data be 2, 10, 18, 25, 15, 16, 15, 3, 27, 17, 15, 16. Cumulative frequency is the running total of frequencies as you move from the lowest to the highest value in a dataset. It helps in understanding the spread of data and identifying percentiles, medians, and quartiles. Learn how to create and interpret cumulative frequency tables and graphs for grouped data sets.
