    • f(28) = 2.15, p < .05; 28 refers to the degrees of freedom, discussed id.,and 2.15 is the t-value. t-tests are used to detect differences between groups using one variable to divide a data set into two groups. The mean for another variable is then calculated for each group. These two means are compared to determine if the difference between them is larger than could be expected by chance.
