To analyze data using a two-way table follow these steps: Watch this lesson multiple times while learning to: To unlock this lesson you must be a Study.com Member. Conditional relative frequency can be found by dividing a joint relative frequency by its related marginal relative frequency, either a row total or a column total. It is called joint frequency because you are joining one variable from the row and one variable from the column. Create a relative frequency table. linear regression is to quantitative variables. 470 Create a relative Worksheet 5.1.4 presents this and the other row conditional 891 permutations. =SUM(C3:C6) in cell C7. 5 When attempting to compare all three types of relative frequencies: Joint, Marginal, and Conditional, one must consider the size of the sample and how the data is spread out. 32.5% Interpret relative frequencies in the context of the data (including joint, marginal, and conditional relative frequencies).
