The program performs three primary functions which may be
executed singly or in any desired combination, i.e. data
storage, histogram construction and analysis of variance
computation. Accepts integer data entered via teletype and
stores these data on LINCtape using the DIAL index. Displays
a histogram of the integers on request using the PDP-12 scope.
Displays minimum, second smallest, second largest and maxi-
mum values of the data array. Computes either a one-factor
repeated measures or a one-factor completely randomized
analysis of variance on the data if requested. This program
package is composed of the following program segments:
$ANOVA, $HISTGM, $INT, $GPH, %AV, %2AV, %3AV.
The package will handle a maximum of 600 numbers at one
time and the largest number of intervals that the histogram
may have is 95.
