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!

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 or http://www.att.com/speedtest/. 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,"... Continue Reading
I've never understood the fascination with selfies.
Maybe it's because I'm over 50. After surviving the slings and
arrows of a half a century on Earth, the minute or two I spend in
front of the bathroom mirror each morning is more than
enough selfie time for me.
Still, when I heard that Microsoft had an online app that estimates
the age of any face on a photo, I was intrigued.
How would the app... Continue Reading
Our vacation planning has begun. My daughter has requested a
trip to Disney World as her high school graduation present.
For most people, trip planning might mean a simple phone call to
the local travel agent or an even simpler do-it-yourself online
Not for me.
As a statistician, a request like this means I’ve got a lot of
data analysis ahead. So many travel questions require (in my... Continue Reading
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

Sure, Minitab Statistical Software is powerful and easy to use,
but did you know that it’s also magic? One of the illusions that
Minitab can perform is the world famous
disappearing-reappearing-analysis-settings act. Of course, as with
many illusions, it’s not so hard once you know the trick. In this
case, it’s downright easy once you know about Minitab project
If you’ve done any work in... 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

The 2014-15 NFL season is only

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

told a friend about my interest in statistics, and he immediately
told me a joke about broiled chicken and statistics.
The punch line involved my friend getting to eat all the
chicken. Unfortunately, I forgot the rest of the joke. I can,
however, assure you it was a very funny statistics-related
People often make jokes when I mention my interest... Continue Reading

Programs such as the Minitab Statistical
Software make hypothesis testing easier; but no program can
think for the experimenter. Anybody performing a statistical
hypothesis test must understand what p values mean in regards to
their statistical results as well as potential limitations of
statistical hypothesis testing.
A p value of 0.05 is frequently used during... Continue Reading
days, my memory isn't what it used to be. Besides that, my memory
isn't what it used to be.
But my incurable case of CRS (Can't Remember Stuff) is
not nearly as bad as that of the exponential distribution.
When modelling failure data for reliability analysis, the
exponential distribution is completely memoryless. It retains no
record of the previous failure of an item.
That might sound like a... Continue Reading
colleague of mine at Minitab, Cheryl Pammer, was recently featured
in "A Statistician's Journey," a monthly feature
that appears in the print and online versions of the American
Statistical Association's AMSTAT News magazine.
Each month, the magazine asks ASA members to talk about the
paths they took to get to where they are today. Cheryl is a "user
experience designer" at Minitab. In other... Continue Reading
