Standard Deviation

Standard deviation is a statistical measure that calculates the amount of variability or dispersion of a set of data values from its mean. It is a measure of the amount of uncertainty or risk associated with the average performance of a dataset. A low standard deviation indicates that the data points tend to be close to the mean, while a high standard deviation indicates that the data points are spread out over a wider range of values. Standard deviation is widely used in data science and artificial intelligence to analyze and interpret data, and to make predictions and decisions based on statistical models. It is an important tool for identifying outliers, detecting patterns, and measuring the accuracy and reliability of data. Standard deviation is also used in machine learning algorithms to evaluate the performance of models and to optimize their parameters.
