Question

You've noticed that when you sleep less, your grades suffer. at the same time, you realize that lower grades could also lead to a lack of sleep: that worrying about a possible dip in your grade point average could keep you up at night. what kind of relationship between the two variables, lack of sleep and lower grades, are you noticing here?

Answer 1

I'm noticing that you don't get lots of sleep and that's why your grades are low. Also, you have to be doing your homework right away and/or study for a test and not being on your phone too much or on any device. 

-Hope this helps!!!

correlation

Explanation:

n statistics, dependence or association is any statistical relationship, whether causal or not, between two random variables or bivariate data. In the broadest sense correlation is any statistical association, though it commonly refers to the degree to which a pair of variables are linearly related.
