To solve this, list all the known integer factors of 12: 3 and 4, 2 and 6, 1 and 12. Now, look at each factor (1, 2, 3, 4, 6, 12) and list a couple of the multiples of 6 which include: 6, 12, 18, 24, 30, etc. When you look back at the factors you notice that 1,2,3, and 4 are not a multiple of 6, therefore 1,2,3, and 4 are the numbers which is a factor of 12 and not a multiple of 6.
To avoid such problems when comparing the categorical variables in a two-way frequency table, we need to exam the table by separate categories (rows or columns). When a relative frequency is determined based upon a row or column, it is called a "conditional" relative frequency.
Two-way relative frequency tables show what percent of data points fit in each category. ...
For example, here's how we would make column relative frequencies:
Step 1: Find the totals for each column.
Step 2: Divide each cell count by its column total and convert to a percentage.
