Elsa Brewer 2022-07-21A sample of n=25 scores has M=20 and . What is the sample standard deviation?
Sample Standard Deviation is a statistical measure used to measure the variation of a set of data from its mean. It can be calculated by taking the square root of the variance of the data set. Sample Standard Deviation is a useful tool in mathematics and statistics to compare the spread of data to that of the entire population. It is also used to detect outliers and other anomalies in data sets. Sample Standard Deviation is an important part of the analysis of statistical data and can be used to draw conclusions and make predictions about the characteristics of a population. It is an important concept for anyone studying mathematics or statistics.
