The sum of all frequencies in a column of a two-way table.

The total of all frequencies in a two-way table, found by adding all row or column totals.

Use the given data to fill in missing values by subtracting from row, column, or grand totals as needed.

Read across rows and down columns to find the frequency of specific combinations of categories.

Ensure all row and column totals add up correctly to the grand total.

Categories could include 'Gender' (rows) and 'Favourite Subject' (columns).
