15.65.3.7 Statistics

- The statistics on the data are typed at the end of the data. This includes the following: 1. Range of data for X and Y 2. Sum of all Y values and average Y value per point. 3. Error in the sum. This is only produced if the Y values have a non zero DY. To specify errors for existing data see the command X. 4. Mean X value, and standard deviation of the mean. Mean=SUM(X*Y)/SUM(Y) Std=SQRT(SUM((X-MEAN)*Y))/SUM(Y) 5. Error on the mean and standard deviation. These are only produced if either DX or DY are non zero for the data. DY is used if available otherwise DX is used to calculate the error. If the number of data points with Y,DX,DY non zero is less than 3 then DX is also used to calculate the error.
