When analyzing data in a 2-way frequency table, you will be looking for joint relative frequency, which is the ratio of the frequency in a particular category to the total number of data values.

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. Here it is all by itself with none of the crazy arrows ...Statisticians also refer to them as two-way tables. Let’s go through examples of frequency tables for different data types. Categorical Data.

A one-way frequency table shows the results of the tabulation of observations at each level of a variable. In Table 3.2, we show one-way tabulations of sex and race for the 40 patients shown in Table 3.1. Three quarters of the patients are males, and over 87 percent of the patients are whites. Table 3.2.
A two-way table is one way to display frequencies for two different categories collected from a single group of people. One category is represented by the rows and the other is represented by the columns. This table can be used to determine the probabilities associated with various possible outcomes involving those two categories.Two-way frequency table. shows the frequencies for data that has two categories.
