The chart shows the number of cars sold per week at a car dealership during the month of June.

Salesperson Week 1 Week 2 Week 3 Week 4
Tim 4 8 2 1
Geena 1 2 7 1
Rafael 2 1 5 4
Sonny 4 1 1 10

How should the data be displayed to make the most convincing argument that sales improved each week?

A. A bar graph of the total car sales per week
B. A box-and-whisker plot of Sonny's sales per week
C. A line graph of each salesperson's sales per week
D. A circle graph showing how many cars each person sold during the month

I think it's either A or B, but I really can't decide.

Since the purpose is to show the number of cars sold each week, there's one clear answer.

The answer must be A.

Thanks so much!

You're welcome.

the answer is A

To determine which option would make the most convincing argument that sales improved each week, let's analyze the data.

Option A suggests displaying a bar graph of the total car sales per week. This would allow us to compare the total number of cars sold each week and see if there is an upward trend.

Option B suggests creating a box-and-whisker plot specifically for Sonny's sales per week. This would show the distribution of Sonny's sales and any potential changes over the course of the month.

Option C proposes a line graph for each salesperson's sales per week. This would allow us to see the individual sales performance of each salesperson and determine if there is a consistent improvement throughout the weeks.

Option D suggests a circle graph showing how many cars each person sold during the month. This option may not provide a week-to-week analysis and might not effectively demonstrate improvement over time.

To make the most convincing argument that sales improved each week, the most appropriate option would be C. A line graph of each salesperson's sales per week would clearly show the sales performance of each individual over four weeks, allowing for easy comparison and identification of any improvement trends.
