Question

describe the residual plot used in question 5. Be sure to include the following in your response. definition of residual labeling of axes in a residual plot how to actually make the plot conclusions drawn from a residual plot

Answer 1

Let me explain it to you this way: A residual plot is basicaly a graph that shows the residuals on the vertical axis and the independent variable on the horizontal axis.Please have in mind that if the points in a residual plot are dispersed around the horizontal axis then what happens is that a linear regression model is appropriate for the data. If this type of graph is not good then a non-linear model is better. If you want to find a residual plot you will need to use the axis Y to find the residual values and you need to use the axis X to find the age. After that you wil find the residual in the plot used in question 5
