You just found a positive trend line showing a strong relationship between homework scores and test scores for five students. Explain what this means.

Answer:

A positive trend line indicates that there is a positive slope between the variables, meaning that as homework scores increase, test scores also tend to increase. Because the relationship is described as strong, the trend line serves as a reliable predictor for how a student might perform on a test based on their homework scores.
