Standard deviation is a statistical measure of the amount of variation or dispersion in a set of data points. it provides a way to quantify how spread out the values in a dataset are from the mean (average). in other words, it measures the average distance between each data point and the mean.
Descriptive Statistics Pdf There are three common ways of describing the centre of a set of numbers. they are the mean, the median and the mode and are calculated as follows. the mean add up all the numbers and divide by how many numbers there are. the median is the middle number. it is found by putting the numbers in order. Specific statistical software where a program handles a particular technique and data are fed in directly. spreadsheet packages, where data are stored in a matrix of rows and columns; a series of instructions can then carry out any technique which the particular package is able to do.
