< 1min

use the number of deviations from the mean (standard scores) to describe deviations from the mean in normally distributed data sets

calculate quantiles for normally distributed data with known mean and standard deviation in practical situations

use the 68%, 95%, 99.7% rule for data one, two and three standard deviations from the mean in practical situations
