Question

the scatterplot shows the relationship between the number of texts a student sends each week and the students gpa which color is the line of best fit for the data points?
which should you consider when informally assessing whether a line is the best fit for the data on a scatterplot?
a the range of the data points
b the median of the data points
c the outliers of the data points
d the closeness of the data points

Explanation:

Step1: Understand the concept of line of best fit

A line of best fit is a straight line that best represents the data on a scatter plot. It should be as close as possible to most of the data points.

Step2: Analyze each line

• The purple line is too far from most of the data points.
• The red line is also not close enough to many data points.
• The orange line is a single vertical line, which is not a proper line of best fit (a line of best fit for a relationship between two variables like GPA and social - media posts should be a non - vertical line).
• The black line is closest to most of the data points.

Answer:

C. black
