College Football Playoff technically doesn't start until December
31st, but in reality it started Saturday night in Indianapolis. The
winner of the Big Ten Championship Game was in the playoff, while
the loser was out. The stakes couldn't have been higher. So the
competitors need to make sure they gain every advantage they can.
And that's where 4th down decisions come in. With a lot of... Continue Reading
There are many reasons why a distribution might not be
normal/Gaussian. A non-normal pattern might be caused by several
distributions being mixed together, or by a drift in time, or by
one or several outliers, or by an asymmetrical behavior, some
out-of-control points, etc.
I recently collected the scores of three different teams (the
Blue team, the Yellow team and the Pink team) after a laser... Continue Reading
P-values are frequently misinterpreted, which causes many
problems. I won't rehash those
problems here here since my colleague Jim Frost has
detailed the issues involved at some length, but the fact remains
that the p-value will continue to be one of the most frequently
used tools for deciding if a result is statistically
You know the old saw about "Lies, damned lies, and... Continue Reading
was a lot at stake in the final week of Big Ten play this week.
Three different games had an impact on not only the Big Ten
Championship Game, but the College Football playoff as well.
Unfortunately for the viewers, none of the games were really close
in the 4th quarter. But that doesn't mean we can't analyze the 4th
down decisions in the first 3 quarters and see whether the losing
teams had... Continue Reading
‘Statistics’ is a rising star. Everywhere I
turn, people are talking about data and the value of being able to
analyze and act on it. As someone who’s been writing about that for
years, I say it’s about time.
Statistics is like a talented
actress whose decades of appearing off Broadway have finally paid
For years, her work has been enriching our lives without us
knowing it. Statistics helps... Continue Reading
This week is the annual Thanksgiving holiday in the United
States, a period where we are encouraged to eat turkey and
cranberries, then consider the blessings in our lives before
falling into a comfortable pre-football nap. That includes many of
us here at Minitab.
we won't have new posts for you over the next two days. But
one of the things I'm grateful for is having had the... Continue Reading
past weekend in the Big Ten showed how being conservative on 4th
down decisions can cost you a game. Ohio State punted on 4th and 1
three different times, while Penn State and Illinois both kicked
field goals in the 4th quarter when they needed a touchdown to tie
or take the lead. All three teams lost. Perhaps taking some advice
from the 4th down calculator would have greatly benefited them!
If... Continue Reading
Back when I was an undergrad in
statistics, I unfortunately spent an entire semester of my life
taking a class, diligently crunching numbers with my TI-82, before
realizing 1) that I was actually in an Analysis of Variance (ANOVA)
class, 2) why I would want to use such a tool in the first place,
and 3) that ANOVA doesn’t necessarily tell you a thing about
Fortunately, I've had a lot more... Continue Reading
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!
Students all over the country are noticing excessive food waste
at their schools and are starting programs to bring awareness and
improve the problem. Naturally, many of these programs have roots
in Lean Six Sigma. In one example, a group of... Continue Reading
use statistics to arm ourselves with more information. That
information allows us to make more informed decisions. And the
sooner we can obtain this information, the better.
For example, suppose one of your manufacturing machines starts
to malfunction and makes your products out of spec. You don't want
to wait until the product reaches customers before you discover
this information. Then it's... Continue Reading
you ever wonder why statistical analyses and concepts often have
such weird, cryptic names?
One conspiracy theory points to the workings of a secret
committee called the ICSSNN. The International Committee for
Sadistic Statistical Nomenclature and Numerophobia was formed
solely to befuddle and subjugate the masses. Its mission: To select
the most awkward, obscure, and confusing name possible... Continue Reading
Control charts are a fantastic tool. These charts plot your
process data to identify common cause and special cause variation.
By identifying the different causes of variation, you can take
action on your process without over-controlling it.
Assessing the stability of a process can help you determine
whether there is a problem and identify the source of the problem.
Is the mean too high, too low,... Continue Reading
time I touched on the subject of
the greatest Super Bowl quarterback, I promised a multivariate
analysis considering several different statistics. Let’s get right
to a factor analysis.
Getting Ready for Factor Analysis
One purpose of factor analysis is to identify underlying factors
that you can’t measure directly. These factors explain the
variation of many different variables in fewer... Continue Reading
Don't be a grumpy cat when something on your capability report
doesn't smell right. After
pressing that OK button to run your analysis, allow your inner cat to
understand how and why certain statistics are being used. To help
you along, here are some capability issues that customers have
brought up recently.

A problem must be understood before it can be properly
addressed. A thorough understanding of the problem is critical when
root cause analysis (RCA) and an RCA is necessary if an
organization wants to implement corrective actions that truly
address the root cause of the problem. An RCA may also be necessary
for process improvement projects; it is... Continue Reading
I have two young children, and I
work full-time, so my adult TV time is about as rare as finding a
Kardashian-free tabloid. So I can’t commit to just any TV
show. It better be a good one. I was therefore extremely
excited when Netflix analyzed viewer
data to find out at what point
watchers get hooked on the first season of various
they identified the episode at which 70% of...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
