The scatterplot shows the relationship between two variables x and y. A line of best fit for the data is also shown. For how many of the 10 data points is the actual y-value greater than the y-value predicted by the line of best fit?

Question

Accepted Answer

Choice C is correct. Any data point that’s located above the line of best fit has a y-value that’s greater than the y-value predicted by the line of best fit. For the scatterplot shown, 6 of the data points are above the line of best fit. Therefore, 6 of the data points have an actual y-value that’s greater than the y-value predicted by the line of best fit. Choice A is incorrect and may result from conceptual or calculation errors. Choice B is incorrect. This is the number of data points that have an actual y-value that’s less than the y-value predicted by the line of best fit. Choice D is incorrect and may result from conceptual or calculation errors.
