Here is an example of a two-way table that shows the number of males and females who like various games: Each entry in the table is called joint frequency and the sum or total of rows and columns is called the marginal frequency. Here, 13, 15 ...Cumulative relative frequency is a statistical calculation figured by adding together previously tabulated relative frequencies that makes a running total along a frequency table, ...

So, it must be that \ (65 – 25 = 40\) were unsure or unlikely to buy. Continuing this process, we can complete the table. The totals on the right, or row totals were found by adding across: \ (25 + 20 + 54 = 99\) and \ (40 + 10 + 31 = 81\). So that’s it! We have made our two way table.
