In  Standard deviation (SD) is the average deviation from the mean in your observed data. It is an index of how individual data points are scattered.

Standard deviation definition is - a measure of the dispersion of a frequency distribution that is the square root of the arithmetic mean of the squares of the deviation of each of the class frequencies from the arithmetic mean of the frequency distribution; also : a similar quantity found by dividing by one less than the number of squares in the sum of squares instead of taking the arithmetic What is Standard Deviation? From a statistics standpoint, the standard deviation of a dataset is a measure of the magnitude of deviations between the values of the observations contained in the dataset. The sample standard deviation distribution is a slightly complicated, though well-studied and well-understood, function.. However, consistent with widespread inconsistent and ambiguous terminology, the square root of the bias-corrected variance is sometimes also known as the standard deviation, Standard deviation formula is used to find the values of a particular data that is dispersed. In simple words, the standard deviation is defined as the deviation of the values or data from an average mean. To find the standard deviation of a set of numbers, first find the mean (average) of the set of numbers: Second, for each number in the set, subtract the mean and square the result: Then add all of the squares together and find the mean (average) of the squares, like this: Finally, take the square root of the second mean: . Standard deviation (usually denoted by the lowercase Greek letter σ) is the average or means of all the averages for multiple sets of data.
