**Question 20**

The variance and the standard deviation must necessarily decrease in response to eliminating the largest value, the smallest value, or (especially) both the largest and smallest values of a dataset.

True

False

Answer #1

6:

Eliminating the largest and smallest data value gives the followng data set:
