Which measure of the center is found by adding every value and dividing by how many there are?
AThe median
BThe mode
CThe mean
DThe range
Answer & Solution
Correct answer: C. The mean
1. Adding up the values and sharing the total out equally is the everyday idea of an average.
2. In statistics that calculation is called the mean.
3. The median instead splits ordered data into halves, so it is found by sorting rather than adding.
