Check out these seven questions to ask yourself before choosing statistical software—your answers should help guide you towards the best solution for your needs! 1.

I blogged a few months back about three different Minitab tools you can use to examine your data over time. Did you know you that you can also use a simple run chart to display how your process data changes over time? Of course those “changes” could be evidence of special-cause variation, which a run chart can help you see. What’s special-cause variation, and how’s it different from common-cause...

The last thing you want to do when you purchase a new piece of software is spend an excessive amount of time getting up and running. You’ve probably been ready to the use the software since, well, yesterday. Minitab has always focused on making our software easy to use, but many professional software packages do have a steep learning curve. Whatever package you’re using, here are three things you...

You can use contour plots, 3D scatterplots, and 3D surface plots in Minitab to view three variables in a single plot.

Ultimately, these three graphs are good choices for helping you to visualize your data and exa... Continue Reading

To celebrate, here’s a roundup of just some of the most influential women in statistics: Florence Nightingale While Florence Nightingale is known as the founder of modern nursing, you might not know that she is also a...

While the roots of Lean Six Sigma and other quality improvement methodologies are in manufacturing, it’s interesting to see how other organizational functions and industries apply LSS tools successfully. Quality improvement certainly has moved far beyond the walls of manufacturing plants! For example, I recently had the opportunity to talk to Drew Mohler, a Lean Six Sigma black belt and senior...

Ahh, bottled water. Refreshing, convenient...and sometimes pricey. Or in my case, I should say usually pricey. Confession: I’m a sucker for water that comes in the “pretty” plastic bottles, and my experience is that the pretty-bottle brands are usually the pricier ones. Does bottled water cost increase with the fanciness of the bottle? Well, that could be an analysis for a different day … My... Continue Reading
According to this article published on Food Tank, over 22 million pounds of food is wasted on college campuses each year. Now that’s a lot of food waste!

Naturally, many of these programs have roots in Lean Six Sigma. In one example, a group of... Continue Reading

In previous posts, I discussed the results of a recycling project done by Six Sigma students at Rose-Hulman Institute of Technology last spring. (If you’re playing catch up, you can read Part I and Part II.) The students did an awesome job reducing the amount of recycling that was thrown into the normal trash cans across all of the institution’s academic buildings. At the end of the spring...

Many things have shocked me since having my first baby back in August. I didn’t think it was possible to be so tired that it actually hurt, and I also didn’t think that changing 10+ diapers a day would actually be the norm (or that needing to perform 10+ outfit changes was even possible, let alone necessary). I also didn’t think that we’d fall in love so hard with the little guy. What a wonderful,... Continue Reading
I left off last with a post outlining how the Six Sigma students at Rose-Hulman were working on a project to reduce the amount of recycling thrown in the normal trash cans in all of the academic buildings at the institution. Using the DMAIC methodology for completing improvement projects, they had already defined the problem at hand: how could the amount of recycling that’s thrown in the normal trash... Continue Reading
I caught the end of Toy Story over the weekend, which is definitely one of my all-time favorite children’s movies. Now—unfortunately or fortunately—I can’t get Randy Newman's theme song,“You’ve Got a Friend in Me,” out of my head! It's also got me thinking about the nature of friendship, and how "best friends forever" are supposed to always be there when you need them. And, not to get too maudlin... Continue Reading

I learned not only about the areas of patient care where they are targeting improvements, but about... Continue Reading

Recently, they published a post covering the... Continue Reading
The Six Sigma students at Rose-Hulman Institute of Technology are at it again! A few months back, we blogged about the Six Sigma project they did to reduce food waste at the on-campus dining center. This time, the students—lead by Dr. Diane Evans, Six Sigma black belt and associate professor of mathematics at Rose-Hulman—are performing a Lean Six Sigma project to reduce the amount of recycling...
