Question

justifying predictions of a scatterplot
can predictions be made of a scatterplot that shows no association? explain your answer.

Explanation:

A scatterplot with no association means there is no relationship between the two variables. Predictions are based on a relationship (like linear, non - linear) between variables. Without an association, there is no pattern to follow for making predictions.

Answer:

No, predictions cannot be made. Since there is no association (no relationship between the variables shown in the scatterplot), there is no basis (no pattern) to predict values of one variable based on the other.
