You are shown a scatter plot where the variables have a positive correlation, but there are no labels on the axes.Which of the following options could be used to label the axes? Select all that apply.A)The amount of money raised by a charity each week.B)The number of softball pitches thrown in games during the season.C)The age of viewers for a weekly television show and minutes watched.D)The height of a toddler after each month. E)The number of hours of babysitting and the amount of money paid.

Answer 1

It's important to know that a positive correlation refers to a relationship between variables when both increase, and we get an increasing function representing that situation, for example, a positive correlation can be modeled by age and height, both variables increase with time.

So, in this case, the answer choice that models a positive correlation is A, D, and E.

Let's analyze each of them.

A. The amount of money raised by a charity each week.

This is a positive correlation because the amount of money increases while time also increases (time can't go backward).

D. The height of a toddler after each month.

This is a positive correlation because the heigh increases with time (as we said in the example at the beginning of the answer).

E. The number of hours of babysitting and the amount of money paid.

This is a positive correlation because the more hours of babysitting more money have to be paid.
