The correct answer is:
Marginal relative frequency.
Explanation:
Joint frequencies are the numbers in the middle of the chart; they are not compared to totals.
Joint relative frequency is the ratio of the frequency in a particular category and the total number of data values.
Marginal frequencies are the numbers on the ends of the rows and columns. They are not compared to the totals.
Marginal relative frequency is the ratio of the sum of the joint relative frequencies in a row or column and the total number of data values. It compares the total from a row or a column to the total of all data values.
The answer is option B "Marginal relative frequency." Marginal relative frequency is the ratio of the sum of the joint relative frequencies in a row or column and the total number of data values it's used in two way frequency tables mainly when it involves percents.
Hope this helps!
