How Do You Figure Out Cumulative Frequency In Statistics?
Stuck on how to figure out cumulative frequency of classes? This step by step guide will help you answer that question without a calculator in less than a minute. Draw a frequency distribution chart. If you do not know how to draw a frequency distribution chart, see “How to construct distribution chart using classes” in the Resources box below before continuing on to step 2. Count the number of items in the first class and write that number below the class column. For example, if you have four items in the first column, write 4 below that column. Add the number of items in the second column and add it to the first column. For example if you have 4 in the first column and six in the second column, the number under your second column would be 10. (This is what is meant by a cumulative total). Keep on adding up the columns to the total. See the graph for an example of cumulative frequency. Look at the bottom of the requested class to get your answer. For example, in the above graph, if yo
