Statistics - Standard Deviation

This document serves as a library write-up for a computer program written in FOCAL designed to perform basic statistical analysis. The program accepts data either through a keyboard or via a paper tape reader. Once the data is entered, it calculates and outputs the mean, variance, standard deviation, coefficient of variation, maximum value, minimum value, and the total count of data points. The document includes detailed instructions for data entry, procedures for correcting errors during input, and the mathematical equations used for the calculations. It also provides sample programs demonstrating keyboard and tape entry methods, along with the source code for the program.
