Calculate standard deviation by computing 1-Variable Statistics for L1 • Press STAT • Press the Right Arrow (highlight CALC) • Choose option “1: 1-Var Stats” • Press enter to compute the 1-variable statistics (defaults to L1). = arithmetic mean of the data set. Σx = sum of the x values. Σx2= sum of the x2 values. Sx = sample standard deviation

Standard Deviation and Variance on a Graphing Calulator
The standard deviation is useful when comparing data values that come from different data sets. If the data sets have different means and standard deviations, it can be misleading to compare the data values directly. For each data value, calculate how many standard deviations the value is away from its mean. Use the formula: value = mean + z
