Relative frequency definition is a fraction showing how often an item appears compared to all other objects. It is called joint frequency because you are joining one variable from the row and one variable from the column. Marginal relative frequency is the ratio of the sum of the joint relative frequency in a row or column and the total number of data values. Categorical variables can be analyzed by using joint, marginal, and conditional relative frequencies. When we look at relative frequency, we are looking at the number of times a specific event occurs compared to the total number of events. | 9 Joint relative frequency is the ratio of a frequency that is not in the total row or the total column to the total number of values or observations. a\^hD.Cy1BYz 2 lines are on the graph.
