Questions students ask
What is the difference between population and sample standard deviation?
The population version divides by n; the sample version divides by n − 1, which corrects for estimating from a sample.
How are outliers found from a box plot?
A common rule: any value more than 1.5 × the interquartile range below the lower quartile or above the upper quartile.
