Histogram and Two-Factor Analysis of Variance

This document provides a technical write-up for a computer program package designed for the PDP-12A system, written in FOCAL-12. The program performs three primary functions: data storage (using LINC tape), construction of histograms (up to 95 intervals for a maximum of 600 data points), and two-factor analysis of variance (ANOVA) computations.

The software supports three specific experimental designs: completely randomized, repeated measures, and mixed designs. The manual outlines the hardware requirements (PDP-12A, two TUS5 tape units, 8K memory), operating instructions, specific entry procedures for different data matrices, and provides the full source code for the program segments required to execute these tasks.
