Calculation of Total Number of Cells in a (m×n) Bivariate Frequency Table

In a bivariate frequency table, the rows represent one variable (m) and the columns represent another variable (n). To calculate the total number of cells in a (m×n) bivariate frequency table, we need to multiply the number of rows (m) by the number of columns (n).

Here's how you can calculate the total number of cells in a (m×n) bivariate frequency table:

Formula:
Total number of cells = m × n

Explanation:
- Each row in the bivariate frequency table represents a unique value of one variable (m), and each column represents a unique value of another variable (n).
- When we multiply the number of rows (m) by the number of columns (n), we get the total number of cells in the table.
- Each cell in the table represents the intersection of a specific value of the row variable with a specific value of the column variable.

Therefore, the correct answer is (D) mn, where mn represents the total number of cells in a (m×n) bivariate frequency table.
