standard score is the average of the standard deviations of the test. The average of the standard deviations of the test is the average of the standard deviations of the test.

The average of the standard deviations of the test is the average of the standard deviations of the test. The average of the standard deviations of the test is the average of the standard deviations of the test. The average of the standard deviations of the test is the average of the standard deviations of the test. The average of the standard deviations of the test is the average of the standard deviations of the test.Worked example: If a test has a mean of 70 and a standard deviation of 10, a score of 85 gives z = (85 − 70) ÷ 10 = 1.5, meaning it is one and a half standard deviations above average.Worked example: If a test has a mean of 70 and a standard deviation of 10, a score of 85 gives z = (85 − 70) ÷ 10 = 1.5, meaning it is one and a half standard deviations above average.Worked example: If a test has a mean of 70 and a standard deviation of 10, a score of 85 gives z = (85 − 70) ÷ 10 = 1.5.Worked example: If a test has a mean of 70 and a standard deviation of 10, a score of 85 gives z = (85 − 70) ÷ 10 = 1.5.Worked example: If a test has a mean of 70 and a standard deviation of 10, a score of 85 gives z = (85 − 70) ÷ 10 = 1.5Worked example: If a test has a standard deviation of 10, a score of 85 gives z = (85 − 70) ÷ 10 = 1.5Worked example
