Question

as part of a school project, jennifer collected data on the rainfall received in her city each day during one month. she wants to identify the amount of rainfall that occurred on the most number of days in that month. which measure of center will jennifer need to find?

○ mean

○ median

○ mode

○ range

Explanation:

To determine the amount of rainfall that occurred on the most number of days, we need to recall the definitions of each measure:

• Mean is the average, calculated by summing all values and dividing by the number of values. It doesn't show the most frequent value.
• Median is the middle value when data is ordered. It represents the middle position, not the most frequent.
• Mode is defined as the value that appears most frequently in a data set. This matches the requirement of finding the rainfall amount with the highest frequency (most number of days).
• Range is the difference between the maximum and minimum values, which shows spread, not frequency.

So, the measure of center needed is Mode.

Answer:

C. Mode
