Tag: standard deviation

Standard deviation is a mathematical concept used to measure variability in a group of numbers. It is used in many different scientific and statistical disciplines to measure the spread of a data set. Standard deviation determines how much variation or deviation exists from the average (mean) of a set of numbers. This measurement is important because it can help researchers identify trends in data, identify outliers, and compare similar data sets. Standard deviation is a key statistic for making decisions about how to interpret data and its associated trends.
