The mean of a population is also known as the
2.
The mean can be calculated by

Listing all terms in numeric order and finding the midpoint
B.
Finding the most common term
C.
Dividing the sum of all terms by the population size
D.
3.
The mode is the most common term. A population can have
4.
To find the median value of a population, the terms must first be ordered numerically.
5.
To find the median of a population with an even number of terms, you must
A.
Find the mean of the two central terms
B.
Choose one of the two central terms
C.
Use the difference between the two central terms
D.
Say that there is no median
6.
A population's mean can also be calculated by multiplying each value by its decimal proportion of the population, and taking the sum of these products
