Can SAT scores predict success in college? Is there a correlation between the amount of ice cream eaten and weight loss? How about the daily number of minutes of exercise and resting heart rates? Learn to evaluate these questions with correlation and regression using Minitab. Determine the strength of the relationships and evaluate the significance of the result. Learn to create graphs to display the regression equation and understand how they can be used for prediction with the help of prediction intervals. Learn to generate residual plots using Minitab to evaluate the validity of the model.
- [Voiceover] In this movie, I will show you how to do…correlation with regression.…Open exercise file 04-06.…We have some data here regarding speed,…driver reaction time, and stopping distance of the vehicle…after the breaks have been applied.…The question of interest here is,…"Does speed affect stopping distance?"…We can do a correlation on that,…and let's plot the data first.…To do that, it will be a scatterplot.…Go up to Graph, Scatterplot, Simple,…and since we are determining…whether speed affects stopping distance,…the y would be the Stopping Distance,…and the x would be the Speed.…
And here's a scatterplot.…It looks like there's a very strong correlation,…a positive one, at that, too,…because as speed increases,…the stopping distance increases too.…So, for correlation, go up to Stat,…Basic Statistics, Correlation,…and the variables you want are Speed,…and Stopping Distance.…You can use the default Pearson correlation…coefficient method.…The other is the Spearman.…So, let's stay with the default.…And here we have it, a very strong correlation coefficient…
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.
