The degree of freedom for an ANOVA (Analysis of Variance) table is determined by the number of groups or treatments and the total number of observations.
In the context of an ANOVA table, the degree of freedom for the numerator (between-groups) is equal to the number of groups or treatments minus 1, denoted as c-1.
The degree of freedom for the denominator (within-groups) is equal to the total number of observations minus the number of groups or treatments, denoted as n-c.
Therefore, the correct answer is a. n-1, which represents the degree of freedom for the numerator in an ANOVA table.
