STANDARD DEVIATION FOR UNGROUPED DATA using calculator CASIO fx 570MS YouTube
Standard deviation in statistics, typically denoted by σ, is a measure of variation or dispersion (refers to a distribution's extent of stretching or squeezing) between values in a set of data. The lower the standard deviation, the closer the data points tend to be to the mean (or expected value), μ. Conversely, a higher standard deviation.
