Twenty cases:

Cases are classified according to one variable, with categories A and B, and also classified according to a second variable with categories 1, 2, and 3. The cases are shown, with the first digit indicating the value of the first variable and the second digit indicating the value of the second variable. (So €˜€˜A1€ represents a case in category A for the first variable and category 1 for the second variable.) Construct a two-way table of the data.
