A test has a mean of 150 and a student performed 1 standard deviation above the mean. What score did the student have on the test?

To answer this question, we need to know the value of the standard deviation. The standard deviation measures the spread or dispersion of data around the mean.

Since we are given that the student performed 1 standard deviation above the mean, we can use the formula:
(student's score) = (mean) + (standard deviation)

Without the specific value of the standard deviation, we cannot calculate the student's score.
