Calculator Steps for TI-84 MAT 1272 These steps outline how to use a TI-84 calculator for MAT 1272. TI82 and TI83 Character Reference. Now, say the mean (x-bar) is 100 and the standard deviation, Sx, is 15. A z-score for a specific measurement, say 130, is (130â100)/15=2. In other words, a result of 130 is two standard deviations away from the mean. So 2 is the z-score for a measurement of 130 if the mean is 100 and the standard deviation is 15. 10 Find the standard deviation value next to Sx or Ïx. You can find the standard deviation of a data set in two ways with your TI-84 Graphing Calculator.
