Question

1. the average (mean) of a data set is calculated by:

a. dividing the sum of all numbers by the count of numbers
b. adding the highest and lowest numbers together

Explanation:

The mean of a data set is calculated by dividing the sum of all the values in the data set by the number of values. Option b describes finding the range (if we were to further subtract the lowest from the highest), option c is the definition of the mode, and option d is not a standard statistical measure for central tendency.
