                                 STATISTICS                HEP6.HLP

    There are two modes  in the statistics program.  In mode  1 the program
    will  ask for  a series  of values.   It  will then  compute the  mean,
    standard deviation and variance for the list of values.

    In mode 2 the program will ask for  a series of points, X and Y values.
    In  addition to  the mean,  standard  deviation and  variance, it  will
    compute the slope and  the Y-intercept for the set of  points.  It will
    also give the "r"  and the "r^2" values.  After entering  all your data
    you can enter an  X value and the program will  compute the predicted Y
    value.

                                Definitions

     Mean = The average of all the values.
     Deviation = The difference between the values and the mean.
     Variance = The average of the squared deviations.
     Standard Deviation = The squared of the variance.
     "r" value = The correlation coefficient.
     "r^2" value = The coefficient of determination.
