Question

HW-02: Problem 7 Previous Problem Problem List Next Problem (1 point) Refer to the previous question, the physics student used the regression model to make a prediction: in order to stretch the spring by 15cm, the force required is predicted to be 377.28N. Remarkably, his prediction was horribly wrong. Can you explain why? (Check all that apply) A. Correlation does not imply causation. B. He made a prediction outside of the range of stretched distances measured. C. He had outliers or influential points in his data. D. He made a prediction outside of the range of forces observed. E. None of the above

Answer 1

Abs:

Correct options are B and C:

He made a prediction outside of the range of stretched distances measured

He had outliers or influential points in his data.

(we can not predict for x values which are out of range of the sampled x values)
