To calculate the degrees of freedom, one must employ which of the following:
A) $ \frac{(\# \text { of rows } - \# \text {of columns })}{2} $
B) (# of rows - 1) x (# of columns - 1)
C) $ \frac{(\# \text { of rows }-1)}{(\# \text { of columns }-1)} $
D) -$ \frac{(\# \text { of rows }-1)}{(\# \text { of columns }-1)^{2}} $

Question

To calculate the degrees of freedom, one must employ which of the following:
A) $ \frac{(\# \text { of rows } - \# \text {of columns  })}{2} $
B) (# of rows - 1) x (# of columns - 1)
C) $ \frac{(\# \text { of rows }-1)}{(\# \text { of columns }-1)} $
D) -$ \frac{(\# \text { of rows }-1)}{(\# \text { of columns }-1)^{2}} $

The formula to calculate the degrees of freedom for a statistical test is (# of rows - 1) x (# of columns - 1). This formula is used for tests such as chi-square tests and ANOVA, where the degrees of freedom are used to determine the critical values for the test statistic. Option A is incorrect as squaring the difference between rows and columns is not necessary when computing degrees of freedom. Option C and D are incorrect as the multiplication of the row and column terms is sufficient to calculate the degrees of freedom.

To Calculate the Degrees of Freedom, One Must Employ Which (# of rows −#of columns )2 \frac{(\# \text { of rows } - \# \text {of columns })}{2} 2(# of rows −#of columns )​
