ki collects data that examines the relationship between outdoor temperature and children’s screen time. she wants to see if warmer temperatures have an effect on how much time children spend on screens.
ki should use a
broken-line graph
scatter plot
to visualize outdoor temperature vs. children’s screen time.

Explanation:

Step1: Understand the purpose of different graphs

A scatter plot is used to show the relationship between two variables. A broken - line graph is used to show the change of a variable over time.

Step2: Analyze the relationship in the problem

Ki wants to see if warmer temperatures (one variable) have an effect on children's screen time (another variable). We need to visualize the relationship between two variables (outdoor temperature and children's screen time).
