Def Of Standard Deviation. Standard deviation is a mathematical term and most students find the formula complicated therefore today we are here going to give you stepwise guide of how to calculate the standard deviation and other factors related to standard deviation in this article. Standard deviation is the measure of dispersion of a set of data from its mean. The higher the dispersion or variability the greater is the standard deviation and greater will be the magnitude of the deviation of the value from their mean. The smaller an investments standard deviation the less volatile it is.
If data values are all equal to one another then the standard deviation is zero. The higher the dispersion or variability the greater is the standard deviation and greater will be the magnitude of the deviation of the value from their mean. Standard deviation definition a measure of dispersion in a frequency distribution equal to the square root of the mean of the squares of the deviations from the arithmetic mean of the distribution. However as we are often presented with data from a sample only we can estimate the population standard deviation from a sample standard deviation. Usually we are interested in the standard deviation of a population. A similar quantity found by dividing by one less than the number of squares in the.
