Cumulative frequency: Here we will learn

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. 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! Calculating cumulative frequency gives you the sum (or running total) of all the frequencies up to a certain point in a data set. This measure is different from absolute frequency, which refers to the number of times a particular value appears in a data set.
