A standard score of 100 would also be at the 50 th percentile rank. The middle half of these standard scores falls between 90 and 110. Wechsler SCALED SCORES have an average (mean) of 10 and a standard deviation of 3.A scaled score of 10 would also be at the 50 th percentile rank.-SCORES have an average (mean) of 50 and a standard deviation of 10. A T-score of 53 would be at the 62 nd percentile rank, Stanine 6. The middle half of T-scores falls between approximately 43 and 57.
The Range Rule. The range rule tells us that the standard deviation of a sample is approximately equal to one fourth of the range of the data. In other words s = (Maximum â Minimum)/4. This is a very straightforward formula to use, and should only be used as a very rough estimate of the standard deviation.uppose we start with the data values of 12, 12, 14, 15, 16, 18, 18, 20, 20, 25. These values have mean of 17 and standard deviation of about 4.1. If instead we first calculate the range of our data as 25 â 12 = 13, and then divide this number by four we have our estimate of the standard deviation as 13/4 = 3.25.
