Kayla is monitoring daily production from four lines at 250, 300, 325, and 375 packages. She wants one measure that describes typical output across these lines. Which method would achieve this?
Take the value that appears most frequently
Use the difference between the smallest and largest
Sum the values and divide by the number of values
Select the largest value and use that as the typical figure
Computing the total of all items and dividing by the number of items provides the arithmetic mean (average), which is suitable for representing the typical production figure. The other options do not accurately capture the central tendency because they either focus on a single data point or a difference rather than the overall set.
