Question

The table below describes students from 200 different colleges. The table shows the results of the subjects who have participated in binge drinking. Fill out the table below:

	Binge Drinker	Non-Binge Drinker	Total
Male	1909		3925
Female		4125	6979
Total	4763	6141

Answer 1

In a 2 x 2 contingency table, each row and each column should add & equal the total. In this table you are always given the total, so to find the missing number, simply subtract the number in the column (or row), with the column's (or row's) total e.g. 3925-1909=2016. Then you can even check your work by adding the 2 numbers in the column (or row) that was also just completed, to make sure it's equal to the total of that other row or column(e.g. 2016+4125=6141. In other words, since it's a 2 x 2 table with only 1 missing number in any row or column, when you complete Grand Total cell. you can either add the 2 numbers in the last column or last row (you should get the same answer for both.
