Midrange calculator
The midrange is the simplest measure of center: average of the smallest and largest values.
Data
Midrange formula
Midrange = (Min + Max) / 2
For {3, 7, 12, 5, 9}: Min=3, Max=12. Midrange = (3+12)/2 = 7.5.
Pros and cons
Simple to compute but highly sensitive to outliers — one extreme value pulls it significantly.
