When calculating an average, what do you do after summing all the values?

• A. Multiply by the number of items
• B. Subtract the smallest value
• C. Divide the total by the number of items
• D. Find the median of the list

Answer: (C)

Calculating the average, also known as the mean, involves a straightforward process after summing all the values in the data set. To find the average, you take the total sum of those values and divide it by the number of items or values that were summed. This step is essential because it evenly distributes the total sum across all items, allowing you to understand the central tendency of the data better. In contrast, multiplying by the number of items would artificially inflate the outcome and does not provide the average. Subtracting the smallest value is not relevant to finding the mean and would not yield useful information about the average. Similarly, finding the median, which involves determining the middle value in a sorted list, serves a different purpose and does not pertain to calculating the mean. Thus, dividing the total sum by the number of items is the necessary and correct step to determine the average.
