You need to display patterns of variation using dotplots, histograms or boxplots. Learn to createthese graphical displays of variation using Minitab. Learn how to display, examine and compare variation in performance of groups, whether that is delivery times, amount of money spent, or duration of calls across groups; groups which may be different suppliers, locations, offices, teams, product categories, or call centers. Dotplots, histograms and boxplots display variation of continuous data across categories or groups. With Minitab, these graphs are relatively easy!
- [Voiceover] In this movie, I will show you how…to create variation plots using Minitab.…Open exercise 02-05, these two vendors…are supposed to deliver within 24 hours.…They both report the mean average time as 23 hours.…Sounds good?…Well, why are you still receiving late deliveries?…So we have to go beyond just one number, the mean…let's plot the data.…And various plots are available to us…to display variation,…these plots are the dot plot,…the histogram, and the box plot.…
Let's begin with a dot plot.…Go up to graph, dot plot…since our data is in two columns,…we'll select multiple, multiple y's, simple…and select those two, and okay.…There you have it, dot plot,…showing the vast differences in…variation between the two vendors.…Even though they both average 23 hours,…I would rather have delivery from vendor B…than from A, who is so inconsistent.…
So let's create the histogram.…To do that go up to graph, histogram, simple.…And graph those two, A and B.…Since we have multiple graphs,…we had to specify how to display them.…
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.
