Question

Which line is the best model for the data in the scatter plot?

Answer 1

Answer C because it's more level with the dots.

Answer 2

Option C is the correct answer.

Explanation:

The line in the option C is the best model for the data in the scatter plot.

Since in this scatter plot the points above and below the line are equally distributed (i.e. there are 5 points above the line and 5 points below the line) whereas in the rest three graphs the distortion above and below the graph is unequal.

i.e. in some the points above the line are more as compared to below the line and in some scatter plot the points below the line are more than above the line.
