Learn to run multiple regressions using Minitab. Answer questions such as: How does vehicle speed and driver reaction time affect stopping distance? If there is a relationship between height and weight, how does gender affect it? These are questions where there are multiple variables possibly affecting an outcome or response. Learn to use Minitab to run multiple regressions to analyze these possible relationships and develop a valid model to predict future performance.
- [Voiceover] In this movie, I will show you…how to do multiple regression using Minitab.…Open Exercise File 04-07.…We have data on Speed, Driver Reaction Time,…and Stopping Distance.…We wanna do a regression of those…two variables against Stopping Distance.…To do that, go up to Stat, Regression,…Regression, Fit Regression Model.…The Response is Stopping Distance, and we have…a choice of Continuous and Categorical predictors.…Since our data set are all continuous,…we'll enter them here, go to Graphs,…and ask for the four in one residual plots.…
This will check your model validity.…OK, and we have the residual plots.…They look very normal and very random, that's good news.…Let's go to our Session window, make this a little bigger.…Going up to the top, we see that we have…the ANOVA table showing the regression…and the two terms, both of which are very significant.…The P-Values show 0.000, which is less than 0.05,…therefore those terms are significant…and they belong in the equation.…
The R-sq values are very high.…
Dr. Richard Chua shows how to import and organize data; open, save, and share Minitab worksheets and projects; create graphs and charts; and use descriptive statistics and statistical tests in Minitab to make inferences and data-driven decisions. Then learn how to make inferences on continuous data—running normality tests, variance tests, correlations, and simple regression tests. Finally, discover how to share your findings with others using reports and simple copy-and-paste techniques. Start watching to learn why Minitab is one of the world's most popular statistical software tools.
