2 standard deviation

Standard deviation is a fundamental concept in statistics that measures the dispersion of data points which defines the extent to which data points in a dataset deviate from the mean, providing a clear sense of the variability or spread within the data.

The standard deviation formula is used to find the deviation of the data value from the mean value i.e.

it is used to find the dispersion of all the values in a data set to the mean value. There are different standard deviation formulas to calculate the standard deviation of a random variable.

In this article, we will learn about what is standard deviation, the standard deviation formulas, how to calculate standard deviation, and examples of standard deviation in detail.

Standard Deviation in Statistics

Standard Deviation is defined as the degree of dispersion of the data point from the mean value of the data point.

It tells us how the value of the data points varies from the mean value of the data point and it tells us about the variation of the
