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.

Idon’t feel like doing the math but you need to do 2.24 divided by 7
