Histogram and Two-Factor Analysis of Variance

This document describes a FOCAL-12 program package designed for the PDP-12 computer. It provides functions for: - Data Storage: Entering and storing integer data on LINC tape. - Histogram Construction: Displaying histograms on the PDP-12 scope. - Statistical Analysis: Computing a two-factor analysis of variance (ANOVA) for completely randomized, repeated measures, or mixed experimental designs.

The package consists of multiple segments ($2ANOVA, $3HSTGM, $4INT, $5GPH, %TFAV, %STFAV, %MD, %RM, %CR, %6CR) and requires 8K of memory and two TUS5 tape units. It includes detailed operational procedures for data entry and model specification.
