Question

For the chi-square test to be effective, the expected value for each cell in the contingency table has to be at least ______.

a) 0
b) 1
c) 5
d) 10

Answer 1

The expected value for each cell in the chi-square test should be at least 5.

Step-by-step explanation:

The expected value for each cell in the contingency table for the chi-square test to be effective should be at least 5.

For example, if you have a 2x2 contingency table, each cell's expected value should be at least 5. If you have a 3x3 table, each cell's expected value should also be at least 5.

This requirement ensures that the chi-square test is reliable and accurate in detecting any significant deviations from the expected frequencies.
