A.1.13.3 Interpreting Measures of Center & Variability

The heights of 40 trees in each of two forests are collected. Here is a comparison of the two data sets using the measure of center and the measure of variability in terms of the situation: The trees in forest B tend to be taller based on mean, but they are also more variable because the standard deviation is greater.
