Which is relatively better: a score of 83 on a psychology test or a score of 55 on an economics test? scores on the psychology test have a mean of 92 and a standard deviation of 13. scores on the economics test have a mean of 56 and a standard deviation of 3?

Your score on the econ test is one unit, or 1/3 of a standard deviation, below the mean.

1/3 of a standard deviation on the psych test is about 4 units. Your score is well below 4 units below the mean of the psych test.

Both scores are below average.

Your econ score is relatively better.
