Question

by visual inspection, determine the best-fitting regression model for the data plot below. A. No pattern B. Quadratic C.Linear D. Exponential

Answer 1

Answer:

C) Linear

Step-by-step explanation:

We can see from the plot that the data approach a straight line.

This means we can draw a line of best fit through this data and it should hit several data points; thus the answer is linear.

Answer 2

This is a goofy question. The data would be well modeled by a linear function which includes a constant offset (y intercept). But a quadratic will actually fit the given data a bit better because there's an extra parameter in the model so more opportunity to capture variance.

I can't see the other choices but I'll guess they want us to answer Linear even though I think it's wrong.
