Learn how to examine and compare the performance of groups using descriptive statistics, whether they are delivery times, amount of money spent, or duration of calls across groups; groups which may be different suppliers, locations, teams, product categories or call centers. Comparing the performance of continuous data across groups using descriptive statistics is very common in business. With Minitab, you don’t need to calculate descriptive statistics, as they are done with just a few clicks of the mouse!
- [Voiceover] In this movie,…I wanna show you how to use Minitab…to calculate descriptive statistics.…Open the exercise file 03-01.…Here we have the delivery time performance…by two suppliers, A and B.…And we're interested in calculating the statistics…such as the mean,…standard deviation,…variance,…the min max.…To do that,…go up to Stat, Basic Statistics,…and Display Descriptive Statistics.…
And here we have the dialogue box.…Select both A and B.…And we can decide what stats you want to display,…so go to Stats…and let's choose mean,…standard deviation,…median,…min max,…and the total number…and click OK.…And there we have it,…performance by the numbers.…Looks like the mean are about the same…for A and B.…The standard deviation, however,…is very different.…Zero point nine three seven for A…and zero point one eight two for B.…
Huge difference.…As you can see,…the min max spread is quite a bit there.…We can also do some graphs to accompany this data.…So, let's do a Control E to our previous dialogue…and ask for graphs.…And let's say we ask for individual value plot.…
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.
