Question

Which scatter plot shows the best line of fit?

Multiple choice question.
A)
B)
C)
D)

Answer 1

To determine the best line of fit in a scatter plot, consider the direction and steepness of the line, and compare it to the trend of the data points.

Step-by-step explanation:

Scatter Plots and Line of Fit

To determine which scatter plot shows the best line of fit, you need to consider the direction and steepness of the line. The scatter plot with the line that closely follows the trend of the data points is the one with the best line of fit. You can also use the calculator's regression function to find the equation of the least-squares regression line and compare it to the scatter plot. The steeper the line, the stronger the correlation between the variables.

Example: In the options A, B, C, and D, choose the scatter plot where the line closely follows the trend of the data points.

Answer 2

D

Step-by-step explanation:

The line of best fit is a line that represents the “average” between all of the points. It’s typically in the middle of all of the points. In this case, I’d go with D because 4 points lie on the line of best fit and the line trends sharply upwards, following the general direction of the points.
