    A scatterplot with a coefficient of determination of 74% indicates a strong relationship between the two variables being plotted. The coefficient of determination, also known as R-squared, measures the proportion of the variance in the dependent variable that can be explained by the independent variable(s). In this case, 74% of the variance in the dependent variable can be accounted for by the independent variable(s), suggesting a strong relationship between the two.

    The residual plot above is : - ProProfs

    The residual plot above is :

    • Linear

    • Non Linear

    • Random

    • Not Random

    • Positive

    • No Relationship

    Correct Answer
    A. Not Random
    Explanation
    The residual plot above is not random. This means that there is a pattern or relationship between the residuals (the differences between the observed and predicted values) and the independent variable(s). The residuals may be consistently positive or negative, indicating a systematic bias in the model's predictions. This suggests that the model may not be capturing all the relevant information or that there may be a missing variable that should be included in the analysis. Further investigation and potential model adjustments are needed to improve the model's accuracy.

    • Random

    • Not Random

    • Positive

    • No Relationship

    Correct Answer
    A. Linear
    Explanation
    The residual plot above shows a linear relationship between the two variables because the residuals are evenly distributed around the horizontal line at zero. This indicates that the model's predictions are consistently above or below the actual values by a constant amount, suggesting a linear pattern in the data.
