Join Richard Chua for an in-depth discussion in this video Solution: Compare inferences on continuous data, part of Learning Minitab.
(tinkling music)…- [Voiceover] To compare these home prices,…we could possibly run a Anova, but before…we can do that, we have to check for normality.…So, Graph, Probability Plot,…Multiple, select the three towns,…and we see the data is not normal.…Besides, home prices are not normal anyway,…so let's go to the nonparametric tests.…In this case it would be the Kruskal Wallis,…because we have three groups.…
Stat, Nonparametrics, Kruskal Wallis.…Given the layout of this dialog,…we have to use stacked data,…but we have stacked data in…Column five and six.…As the comments indicated here,…so choose Prices, factor is Location, okay.…Let's pull this down, and we see that…the result is significant, with a P value…of 0.000, therefore the home prices…are different.…The second question was, which town's…the cheapest?…Well, you can do confidence intervals on…the median, and to do that we go to…Stat, Nonparametrics, choose a…1-Sample Wilcoxon, but we'll use the…confidence interval feature there.…
Confidence interval, there you are,…
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.
