A sample of 100 people is classified by gender (male/female) and by whether or not they are registered voters. The sample consists of 80 females and 20 males, and has a total of 60 registered voters. If these data are used for a chi-square test for independence, what is the total number of females for the expected frequencies?

Solution

There will still be 80 females in the total expected frequencies. [ANSWER, 80]

In expected frequencies, the totals of columns/rows do not change, it\'s just the individual expected values in cross-categories that change.
