Student Test Analysis

This document describes a three-part software program written in FOCAL 4K for the analysis of student test results.

Key Features:

• Part I: Scores individual parts of an exam and prints student scores along with class performance percentages for each question.
• Part II: Aggregates scores from all exam parts to calculate student totals, class means, standard deviations, and decile distributions (including a visual plot).
• Part III: Computes the distribution of answers for specific questions, showing the percentage of the class that chose each answer.

Implementation Details:

• Data Input: Uses punched paper tape with a specific format for key data and student responses.
• Patching: Includes a required patch to the input buffer to prevent overflows during tape reading operations.

This utility was contributed to the DECUS Program Library in 1971 by Dr. Stephen J. Mayor of the Medical College of Ohio at Toledo.
