How do I determine the significance of individual scores from

dependent t test results?

I did a t test with a group (8 students) before and after

experimental treatment.

The pretest-posttest scores were as follows:

-----------------------------------------

Student / Test 1 / Test 2

A / 23 / 27

B / 19.5 / 30

C / 18 / 22

D / 21 / 23.5

E / 29.5 / 35.5

F / 32.5 / 33

G / 13 / 15

H / 28 / 32.5

--------------------------------------------------

The mean test score improvement was 4.25, and standard deviation

was 2.8394.

The t score was -3.96 (df = 7) and the p values were:

P - one-tailed = 0.0027305

P - two-tailed = 0.005461b

Thus, there was statistically significant improvement for the group.

Though all students improved to some degree, how do I determine

which ones made statistically significant improvement?

Thanks a million,
