Question

The table shows the results of a survey of 400 random people on whether they like liquid soap, bar soap, or both. Which is the marginal relative frequency for the people who do not like bar soap?

Answer 1

The marginal relative frequency for the people who do not like bar soap is 100/400. The 100 means the total number of the last column of data values and the 400 means the total number of the last row of data values. Marginal relative frequency is the ratio of the total of the joint relative frequency in a column or row and the overall figure of data values. Joint relative frequency on the other hand describes is the ratio of the number of in a particular set and also the sum of the values of that set.
