As a standard score gives a position in relationship to a reference group, the score by itself is meaningless without knowing the position of the student when compared to all students who took the same test. A standard score of 90, the beginning of the average range, corresponds to a percentile rank of 25.A standard score of 110, the uppermost end of average, has a percentile range of 75. So a child at the 30 th percentile on a test of reading or math is performing within the region of what would be considered âaverage.â.With percentile ranks and standard scores, the comparison group matters.s a standard score gives a position in relationship to a reference group, the score by itself is meaningless without knowing the position of the student when compared to all students who took the same test.

For example, suppose your data is all of the ACT scores of the students in a small class. Then the standard deviation formula is Suppose the scores are 15, 21, 21, 21, 25, 30, and 35. The mean of this set is 24.8, 88, 67, 90, 92, 83, 97. The highest test score is 97 and the lowest is 67, therefore the range is 97-67 = 30. The standard deviation is another way to measure how close together the elements are in a set of data. The s.d. is the average distance between each data point and the mean.
