Question

If I obtain a score of 100 on a test that has a mean of 120 and a standard deviation of 10, what is my standard score?  What would be my T score (mean of 50 and standard deviation of 10)?

Answer 1

z = (100 - 120) / 10

z = -20 / 10

z = -2   (not too good!)

t = 10z + 50

 

You calculate t
