Question

Jes used GeoGebra to find a linear model (trend line) of the data collected for their science project. They calculated the following residuals for their data 0.26, 0.93, 0.5489, and 0.659. What conclusion can Jes make about the appropriateness of the linear model based on the residuals?(1 point)

The linear model does not accurately represent the data since all residuals are positive.

Answer 1

The linear model does not accurately represent the data since all residuals are positive — residuals should be randomly scattered around zero (both positive and negative); all positives indicate a systematic bias (model underestimates).
