What is the formula for finding residuals? - y-yhat=residual When do you know a residual graph is over predicting? - When the point on the residual graph is below the x-axis, meaning that it's negative. When do you know a residual graph is under predicting? - When the point on the residual graph is above the x-axis, meaning it is a positive number How do you know a relationship between x & y is positive? - If the slope is positive, the graph is positive, so that means it's a positive rel...
