The phrase
"standard deviation" refers to a measure that helps us understand how spread out or scattered a set of data points is. It tells us how much the individual data points differ or deviate from the average or mean value. A smaller
standard deviation means the data points are closer to the average, while a larger
standard deviation indicates more variability or dispersion among the data points.
