This document contains the source code and documentation for a collection of five statistical programs for the PDP-8 or PDP-12 systems, written in FOCAL '69. The library includes:

• Student's T Test: Calculates the t-value and degrees of freedom.
• Dunnett's T-Test: Performs multiple comparisons to a control group.
• Normalized Plot Routine: Plots normalized data on a teletype or terminal.
• Mean and Standard Deviation: Standard descriptive statistical calculation.
• Analysis of Variance (ANOVA): Performs single variable analysis of variance for grouped data.

The programs are designed to be run from a teletype or keyboard input.
