A researcher uses an ANOVA to evaluate the mean difference between two treatments and obtains F(1,22)= 4.00.If the researcher had used an independent-measures t test to evaluate the data,what t value would be obtained?
A)t(22) = 2.00
B)t(22) = 16.00
C)t(23) = 2.00
D)t(23) = 16.00

The t value can be calculated from the F value in an ANOVA when comparing two means by taking the square root of F. Therefore, t = sqrt(F) = sqrt(4.00) = 2.00. The degrees of freedom for a t-test comparing two independent means is the same as in the ANOVA, which is 22 in this case.
