Question

Is the line shown on the scatter plot a good line of fit?

Answer 1

The line drawn is a good fit as it follows the pattern of the data but excludes the outlier .

Explaining the line of fit

A good line of fit minimizes the sum of the squared distance between the point and the linear graph.

The line of fit drawn for the graph follow that trend of the plotted data points on the graph. The line minimizes the the sum of the squared distances by passing through the majority of the data points on the scatter plot and ignoring the extreme values.

Hence, the most appropriate option is A.

Answer 2

It is the first answer.

Explanation:

The second answer is incorrect, because this has a negative slope which means that it has a negative association.

The third one is wrong because you can see that it does show that most of the points are clustered around a path that would be a line through the points.

The line of best fit does not have to go through any of the original points.
