Standard score. In statistics, the standard score is the signed number of standard deviations by which the value of an observation or data point is above the mean value of what is being observed or measured. Observed values above the mean have positive standard scores, while values below the mean have negative standard scores. The standard score is a dimensionless quantity obtained by subtracting the population mean from an individual raw score and then dividing the difference by the population standard deviation.
Keep in mind that incorrect answers donât count against you, as they do on your SAT score, so it is beneficial to answer every single question on the test, even if you have no idea which answer is correct. The test grader only counts the right answers for the raw score. Your raw scores for each section are then converted into âscaled scores.â The ACT test score scale ranges from 1 (low) to 36 (high). Each raw score is converted to this scale and rounded up to the nearest whole number.
