Psychology Glossary. Standard Deviation. Standard Deviation is a measure of variation (or variability) that indicates the typical distance between the scores of a distribution and the mean. Looking at an example will help us make sense of this. Assume a professor is interested in the satisfaction of students in her psychology class.
Sample Standard Deviation. A standard deviation of a sample estimates the standard deviation of a population based on a random sample. The sample standard deviation, unlike the population standard deviation, is a statistic that measures the dispersion of the data around the sample mean.tandard deviation refers to the amount of dispersion in a given data set. Researchers calculate the standard deviation of a data set by taking the square root of the variance, and the numerical result is indicated by the letter S. They use the term âvarianceâ to describe the extent of the data spread.
