The symbol σ, often referred to as sigma, represents the standard deviation in statistics. It quantifies the amount of variation or dispersion in a set of values, providing insight into how much individual data points differ from the mean. A smaller σ indicates that the data points are closer to the mean, while a larger σ signifies greater variability. This concept is crucial for understanding the normal distribution, where σ helps define the spread of data around the mean.
congrats on reading the definition of σ. now let's actually learn it.
