Cumulative frequency


Really Dumb




Cumulative frequency
Sure! Cumulative frequency just means adding up all the frequencies (or how many times something happens) up to a certain point. For example, let’s say you have a class of 20 students and you’re counting how many students scored a certain grade on a test. If 5 students got an A, 10 students got a B, and 5 students got a C, the cumulative frequency for an A would be 5 (because 5 students got an A), for a B would be 15 (because 5+10=15 students got an A or a B), and for a C would be 20 (because 5+10+5=20 students got an A, a B, or a C). An analogy for cumulative frequency could be like climbing up stairs. Each step represents a frequency, and when you reach a certain step, you’ve added up all the steps before that. A verifiable fact about cumulative frequency is that it is often used in statistics to analyze data and see patterns or trends.
