The mean, while a crucial statistic that gives us the average of our data set, does not measure how spread out or tightly clustered the data are. Instead, measures like the IQR (Interquartile Range), range, and standard deviation are specifically designed to capture variability within the data.
Understanding these concepts can be incredibly handy in real-world applications! For instance, in finance, investors use standard deviation to assess how volatile a stock’s returns are, helping them gauge risk and make informed decisions on where to put their money.
