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. Trees in forst A will be a littel more uniform than in forest B.
