About this document
Standar Deviasi Data Berkelompok by Bingu Jiddan is a document available to read on EtoBox.
Standard deviation is a measure of how spread out numbers are. It is calculated by taking the square root of the variance. For grouped data, standard deviation is calculated by finding the average deviation from the mean, adjusting for group sizes. The document provides an example of calculating standard deviation for grouped data by first determining the class midpoints and frequencies, then using those values to calculate the sums needed in the standard deviation formula.
