The season of change is upon us here at Minitab's World
Headquarters. The air is crisp and clear and the landscape is
ablaze in vibrant fall colors. As I drove to work one recent
morning, I couldn't help but soak in the beauty surrounding me and
think, "Too bad everything they taught me as a kid was a lie."
see, as a boy growing up in New Hampshire, I was told that the
sublime beauty of autumn... Continue Reading
Pareto charts are a special type of bar chart you can use to
prioritize almost anything. This makes them very useful in making
sound decisions. For example, if you have several possible quality
improvement projects, but not enough time or people to do them all
now, you can use a Pareto chart to identify which projects have the
most potential for making meaningful improvement.
Pareto charts look... Continue Reading
If your work involves quality improvement, you've at least
heard of Design of Experiments (DOE). You probably know
it's the most efficient way to optimize and improve your process.
But many of us find DOE intimidating, especially if it's not a tool
we use often. How do you select an appropriate design, and ensure
you've got the right number of factors and levels? And after you've
gathered your... Continue Reading
No matter how experienced you are at analyzing data,
communicating about your results can be a tremendous challenge. So
it's not surprising that "Effectively Reporting Your Data Analysis"
was one of the best-attended sessions at the inaugural Minitab
Insights Conference last month.
The presenters, Benjamin Turcan and Jennifer Berner of First
Niagara Bank, have a great deal of experience improving...Continue Reading
Every day, thousands of people withdraw extra cash for daily
expenses. Each transaction may be small, but the total amount of
cash dispersed over hundreds or thousands of daily transactions can
be very high. But every bank branch has a fixed cash flow, which
must be set without knowing what each customer will need on a given
day. This creates a challenge for financial entities. Customers
expect... Continue Reading
October 16–22 is National Healthcare Quality Week, started by
the National Association for Healthcare Quality to increase
awareness of healthcare quality programs and to highlight the work
of healthcare quality professionals and their influence on improved
patient care outcomes.
This event deserves your attention because the quality of
healthcare affects every one of us, and so does the cost of... Continue Reading
A reader asked a great
question in response to a post I wrote
about Pareto charts. Our readers typically do ask great questions,
but this one turned out to be more difficult to answer than it
My correspondent wrote:
My understanding is that when you have count data, a
bar chart is the way to go. The gaps between the bars emphasize
that the data are not measured on a continuous scale.... Continue Reading
The ultimate goal of most quality improvement projects is clear:
reducing the number of defects, improving a response, or making a
change that benefits your customers.
We often want to jump right in and start gathering and analyzing
data so we can solve the problems. Checking your measurement
systems first, with methods like attribute agreement analysis or
Gage R&R, may seem like a needless waste... Continue Reading
If you were among the 300 people who attended the first-ever
Minitab Insights conference in September, you already know how
powerful it was. Attendees learned how practitioners from a
wide range of industries use data analysis to address a variety of
problems, find solutions, and improve business practices.
In the coming weeks and months, we will share more of the great
insights and guidance shared... Continue Reading
Face it, you love regression analysis as much as I do.
Regression is one of the most satisfying analyses in Minitab:
get some predictors that should have a relationship to a response,
go through a model selection process, interpret fit statistics like
adjusted R2 and predicted R2, and make
predictions. Yes, regression really is quite wonderful.
Except when it’s not. Dark, seedy corners of the data... Continue Reading
We’ve got a plethora of case studies showing how businesses from different

I confess: I'm not a natural-born decision-maker. Some people—my
wife, for example—can assess even very complex situations, consider
the options, and confidently choose a way forward. Me? I get
anxious about deciding what to eat for lunch. So you can imagine
what it used to be like when I
needed to confront a really big decision or problem. My approach,
to paraphrase the Byrds, was "Re:... Continue Reading
other day I was talking with a friend about control charts, and I

There may be huge potential benefits waiting in the data in your
servers. These data may be used for many different purposes. Better
data allows better decisions, of course. Banks, insurance firms,
and telecom companies already own a large amount of data about
their customers. These resources are useful for building a more
personal relationship with each customer.
Some organizations already use... Continue Reading
The Centers for Medicare and Medicaid Services (CMS) updated
their star ratings on July 27. Turns out, the list of hospitals
provide a great way to look at how easy it is to get random samples
from data within Minitab.
Say for example, that you wanted to look at the association
between the government’s new star ratings and the safety rating
scores provided by hospitalsafetyscore.org. The CMS score... Continue Reading
When I blogged about
automation back in March, I made my husband out to be an
automation guru. Well, he certainly is. But what you don’t know
about my husband is that while he loves to automate everything in
his life, sometimes he drops the ball. He’s human; even I have to
cut him a break every now and then.
On the other hand, instances of hypocrisy in his behavior tend
to make for a good story.... Continue Reading
