. Web Standard deviation is a measurement of dispersion in statistics. Standard error is a statistical term that measures the. It is calculated as.

The MSE either assesses the quality of a predictor ie a function mapping arbitrary inputs to a sample of values of some random variable or of an estimator ie a mathematical function mapping a sample of data to an estimate of a parameter of the population from which the data is sampled. The sum of the scores is divided by the number of values N100 for this example to estimate the mean ie XN mean. The standard deviation is a measure of how widely values are dispersed from the average value the mean.

It indicates how close the regression line ie the predicted values plotted is to the actual data values. It gives an idea about the amount of data in a given data set that is dispersed from the mean.
