## WebsWeWeave 2 years ago Which data sets have a negative correlation? a. The number of visitors at an amusement park and the length of the lines for the rides. c. The temperature and the number of people wearing coats. b. The amount of speed over the speed limit when you get a speeding ticket and the amount of the fine for speeding. d. The distance you live from school and the amount of time it takes to get to school.

let's go through these one by one

2. WebsWeWeave

alright??

3. jim_thompson5910

as the number of people increase, do the lengths of the lines increase?

4. WebsWeWeave

yea

5. jim_thompson5910

so that suggests we have a positive correlation (one variable goes up, the other goes up as well)

6. jim_thompson5910

so choice A is out

7. WebsWeWeave

k

8. jim_thompson5910

so you need to find one where as one variable goes up, the other goes down

9. jim_thompson5910

or vice versa

10. WebsWeWeave

is it b?

11. jim_thompson5910

for instance The distance you live from school and the amount of time it takes to get to school is a positive correlation because as the distance goes up, the time goes up as well

12. jim_thompson5910

yes

13. jim_thompson5910

temp goes up ----> # of people wearing coats goes down

14. WebsWeWeave

oh okay
