### Example Question #1 : Use Measure Of Center And Measure Of Variability To Compare Populations: Ccss.Math.Content.7.Sp.B.4

Two businesses monitored their profits for a week. Which business made the most profit, and what was the average profit per day of that business?

Explanation:

This is a two part problem. First, we need to find out which business made the most profit during the week. To do this, we simply add up the profits from each day:

To solve for the mean, we can take our added profits and divide them by the number of addends, which is :

### Example Question #7 : Use Measure Of Center And Measure Of Variability To Compare Populations: Ccss.Math.Content.7.Sp.B.4

A teacher is comparing two students' median test scores, as show in the dot plots below. Which student had a higher median score, and what was this student's median score?

Student B-

Student A-

Student A-

Student B-

Student A-

Explanation:

The median is the middle number of a set of data points.

To solve for the median, we list our data points in order from least to greatest, and then find the number in the middle.

Student A:

Student B:

Student A has the higher median score,
