WebMultiple Regression Residual Analysis and Outliers. One should always conduct a residual analysis to verify that the conditions for drawing inferences about the coefficients in a linear model have been met. Recall that, if a linear model makes sense, the residuals will: have a constant variance. be approximately normally distributed (with a ...

WebStudents practice interpreting linear models, scatterplots, and residual plots by answering questions about quantitative data in this self-checking color activity. Students are given scatterplots or residual plots and use reasoning and computation to answer questions about linear models fit to data from two quantitative variables. WebNo! A high R-squared does not necessarily indicate that the model has a good fit. That might be a surprise, but look at the fitted line plot and residual plot below. The fitted line plot displays the relationship between semiconductor electron mobility and the natural log of the density for real experimental data.
