How do you calculate the mean of a set of numbers?

• A. Multiply the numbers together
• B. Add the numbers and divide by their count
• C. Subtract the smallest from the largest
• D. Count the numbers only

Answer: (B)

To calculate the mean of a set of numbers, you begin by adding all the numbers together to find their total sum. Once you have this total, you divide it by the count of numbers in the set. This process provides the average value, which is what we refer to as the mean. For instance, if you have a set of numbers like 4, 8, and 6, you would first add them: 4 + 8 + 6 equals 18. Then, since there are three numbers in this set, you would divide 18 by 3, yielding a mean of 6. This method is a foundational concept in statistics, allowing for a representative value that summarizes the data set effectively.
