jimthompson5910 (jim_thompson5910):

as amount of education goes up, in general, annual salary goes ____

jimthompson5910 (jim_thompson5910):

down? or up?

OpenStudy (anonymous):

im working on scatter plots so it doesnt say whether it goes down or up

jimthompson5910 (jim_thompson5910):

I know, but think about it would you earn more with a high school diploma or with a PhD ?

OpenStudy (skullpatrol):

On average.

jimthompson5910 (jim_thompson5910):

yes of course, on average since outliers are possible

im confused>.<

OpenStudy (skullpatrol):

Do you know what a "trend" is?

OpenStudy (anonymous):

yea

jimthompson5910 (jim_thompson5910):

The more time you spend in school, the more you learn so that means you are more likely to make more money if you stay in school, agreed?

OpenStudy (anonymous):

yea

OpenStudy (skullpatrol):

As one increases the other increases is called a POSITIVE trend.

OpenStudy (anonymous):

ok thank you

jimthompson5910 (jim_thompson5910):

so if you had a scatter plot that had "number of years in school" on the x axis and "salary" on the y axis, then it might look like this |dw:1363916327656:dw|
