Xlist, Ylist is the list of independent and dependent variables. The list containing the Freq
(frequency) values for the data is stored in List . The default is 1. All elements must be
real numbers. Each element in the Freq list is the frequency of occurence for each
corresponding data point in the input list specified in the List fields. RegEQ (optional) is
the designated Yn variable for storing the regression equation. StoreRegEqn (optional)
is the designated variable for storing the regression equation. The C level is the
Confidence level probability with default = .95.

ANOVA( (one-way analysis of variance; item H ) computes a one-way analysis of variance
for comparing the means of two to 20 populations. The ANOVA procedure for comparing
these means involves analysis of the variation in the sample data. The null hypothesis
