In Chi-Square Analysis, the Greater the Number of Cells, the Larger

In chi-square analysis, the greater the number of cells, the larger the degrees of freedom. The greater the number of cells, the more opportunity exists to calculate a large chi-square value. In other words, the chi-square value can be "inflated" not due to a real association but simply due to the fact that there are more cells in the analysis. This is why degrees of freedom are used to:

A) determine how many cells you should analyze.
B) determine whether or not the computed chi-square value should be used for a post hoc test.
C) determine whether or not the chi-square value has a probability high enough to support, or not support, the null hypothesis.
D) lower the chi-square value in terms of its level of importance.
E) calculate expected values.
