Could you explain the details about standard error, standard deviation, and the whisker lines??
Whiskey lines are a measure of spread. Anything outside the whisker lines is an outlier.
Standard deviation is the typical distance a point is away from the mean. We almost never know the “true standard deviation” since we don’t have a census but a sample and “standard error” is an approximation of the standard deviation. An error bar made of 2 standard errors go in each direction and they tell u we are 95% confident that the actual value of between there bars.
