I write about how statistics can be used to help understand sports, but these techniques and tools have applications in quality improvement and any other endeavor that involves the analysis of data. Continue Reading »
I’ve been using process analysis to develop a draft strategy for
Fantasy Football. I’ve already
shown that getting a top running back should be your first
priority. But what if the top running backs are gone by the time
you get your first pick? When should you switch to other positions?
I’ll use Minitab to find out.
Analyzing the Data
I’ll look at standard deviations, which measure the spread in
the... Continue Reading
Now that it looks like we’re going to have an NFL season, it’s
time for Minitab to start thinking about Fantasy Football! Many
businesses use process
analysis to improve performance, so why can’t we do the same
thing with the process of selecting a Fantasy Football team? The
answer is, we can! I’ll use process analysis to show how you can
improve the process of drafting your team.
In the Fantasy... Continue Reading
The great Homer Simpson once said "People can come up
with statistics to prove anything." But an accurate statistical
analysis can show significant results. So whether you're making
improvement decisions or simply studying a subject that you're
interested in, make sure you collect data that that eats the entire
doughnut. Erm, I mean, paints the entire picture.
I’ve used ANOVA and... Continue Reading
Whether we're talking about process improvement or sports,

NFL is frequently assumed to be the... Continue Reading

sports or the best way to improve a process through Lean Six Sigma,
it's good practice to verify things you "know" with some data.
Quick and easy data analysis sometimes reveals that what everyone
took as common knowledge just isn't true.
On the other hand, looking at data also can confirm your
suspicions.For example, it's no secret that LeBron James didn't play well... Continue Reading
A recent study by Bank of America found that the proportion of
Americans under 50 on Facebook is 96%. However, the second
paragraph of the article questions the validity of the study. It
A total of
418 participants were included in the polling. Such a limited
sample size will surely bolster calls that the survey was
statistically unreliable, but the persons questioned were supposed
to... Continue Reading
When I was in middle school, I picked up the
newspaper to read an article on the opponent our varsity football
team was playing that night (for our younger audience, this is what a
newspaper is). The article said the opposing team’s running
back was averaging almost 6 yards per carry, which is very high. I
decided that I wanted to keep stats during the game to see if he
was able to average 6 yards... Continue Reading
