now I’m enjoying my daily dose of morning joe. As the steam rises
off the cup, the dark rich liquid triggers a powerful enzyme
cascade that jump-starts my brain and central nervous system,
delivering potent glints of perspicacity into the dark crevices of
my still-dormant consciousness.
Feels good, yeah! But is it good for me? Let’s see what the

T'was the season for toys recently, and Christmas day found me
playing around with a classic, the Etch-a-Sketch. As I noodled with
the knobs, I had a sudden flash of recognition: my drawing reminded
me of the Empirical CDF Plot in Minitab Statistical Software. Did you just ask,
"What's a CDF plot? And what's so empirical about it?" Both very
good questions. Let's start with the first, and we'll... Continue Reading
Did you ever get a pair of jeans or a shirt that you liked, but
didn't quite fit you perfectly? That happened to me a few months
ago. The jeans looked good, and they were very well made, but it
took a while before I was comfortable wearing them.
I much prefer it when I can get a pair with a perfect fit, that
feel like I was born in them, with no period of
So which pair do you think I... Continue Reading

I know that Thanksgiving is always on the last Thursday in
November, but somehow I failed to notice it was fast approaching
until the Monday before Thanksgiving. This led to frantically
sending a last-minute invitation, and a hunt for a turkey.
I live in Germany and this greatly complicated the matter. Not
only is Thanksgiving not celebrated, but also actual turkeys... Continue Reading
If you’re in the market for statistical software, there are many
considerations and more than a few options for you to evaluate.
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. Who uses statistical software in your organization?
Are they expert statisticians, novices, or a mix of both?... 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
You need to consider many factors when you’re buying a used car.
Once you narrow your choice down to a particular car model, you can
get a wealth of information about individual cars on the market
through the Internet. How do you navigate through it all to find
the best deal? By analyzing the data you have available.
Let's look at how this works using
the Assistant in Minitab 17. With the... Continue Reading
If you've used our software, you’re probably used to
many of the things you can do in Minitab once you’ve fit a
model. For example, after you fit a response to a given model for
some predictors with Stat > DOE > Response Surface
> Analyze Response Surface Design, you can do the
Predict the mean value of the response variable for new
combinations of settings of the predictors.
Draw... Continue Reading
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... Continue Reading
As a recent graduate from Arizona State University with a degree
in Business Statistics, I had the opportunity to work with students
from different areas of study and help analyze data
from various projects for them.

had gathered from other students, and they wanted to see if their
new student program was beneficial. I would... Continue Reading
live with a German national, who often tells me that we Americans
spend way too much of our lives at work. He also
frequently comments that we work much less efficiently than Germans
do, during the increased time we’re at work.
Which reminds me—I need to pay my water bill online...
Okay, I’m back. Quick, wasn’t it? So convenient. Now, where was
I? Oh, work habits.
After checking the hourly weather... Continue Reading
I am a bit of an Oscar fanatic.
Every year after the ceremony, I religiously go online to find out
who won the awards and listen to their acceptance speeches. This
year, I was so chuffed to learn that Leonardo Di Caprio
won his first Oscar for his performance in The Revenant in
Awards—after five nominations in previous ceremonies. As a
longtime Di Caprio fan, I still remember... Continue Reading
After my husband’s most recent visit to the dentist, he returned
home cavity-free...and with a $150 electric toothbrush in
I wanted details.
It began innocently. His dreaded trip to the dentist ended in
high praise for no cavities and only a warning to floss more. That
prompted my programming-and-automation-obsessed husband, still in
the chair, to exclaim, "I wish there was a way to automate... Continue Reading
How deeply has statistical content from Minitab blog posts (or
other sources) seeped into your brain tissue? Rather than submit a
biopsy specimen from your temporal lobe for analysis, take this
short quiz to find out. Each question may have more than one
correct answer. Good luck!
of the following are famous figure skating pairs, and which are
methods for testing whether your data follow a... Continue Reading
and 1. It's a situation where the
Big Ten 4th down calculator will never say to kick
(unless, of course, it's the end of the game and a field goal will
tie or take the lead). But what would it take to have the
statistics suggest a punt? The key here is how far the punt
travels. Last year the average Big Ten punt traveled about 40
yards. Using this value, in your own territory you'll score... Continue Reading
I started out on the blog, I spent some time
showing some data sets that would be easy to illustrate
statistical concepts. It’s easier to show someone how something
works with something familiar than with something they’ve never
thought about before.
Need a quick illustration to share with someone about how to
summarize a variable in Minitab? See if they have a magazine on
their desk, and... Continue Reading
Ever use dental floss to cut soft cheese? Or Alka Seltzer to
clean your toilet bowl? You can find a host of nonconventional uses for ordinary objects
online. Some are more peculiar than others.
Ever use ordinary linear regression to evaluate a response
(outcome) variable of counts?
Technically, ordinary linear regression was designed to evaluate
a a continuous response variable. A continuous... Continue Reading
Every now and then I’ll test my
Internet speed at home using such sites as http://speedtest.comcast.net. My need to perform these tests could
stem from the cool-looking interfaces they employ on their site, as
they display the results using analog speedometers and RPM meters.
They could also stem from the validation that I need in "getting
what I am paying for," although I realize that there are... Continue Reading
