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.

We will be looking at the range, quartiles, variance, absolute deviation and standard deviation. Range. The range is the difference between the highest and lowest scores in a data set and is the simplest measure of spread. So we calculate range as: Range = maximum value - minimum value. For example, let us consider the following data set: The maximum value is 85 and the minimum value is 23. This results in a range of 62, which is 85 minus 23. Whilst using the range as a measure of spread is limited, it does set the boundaries of the scores. This can be useful if you are measuring a variable that has either a critical low or high threshold (or both) that should not be crossed. The range will instantly inform you whether at least one value broke these critical thresholds.
