Statistics doesn't always click right away. It's a different way of looking at the world, and I learn something new every time I revisit a quality tool or quality analysis technique. Continue Reading »
The other day a colleague of mine mentioned a use for Minitab's
Tally command that I didn't know about. I thought I would share it
with you in the form of contrived anecdote. I hope you enjoy
Bob works at a manufacturing plant. You may remember Bob as the guy
who was obsessed with gnomes. Well, his work with
gnomes was so exemplary that he was promoted to work in the Garden

I am an outlier. Of the people who work in my department, I go
to the fewest meetings, I talk with others the least, and I make
the least use of our exercise facilities. But this is not because I
am negligent, anti-social, or lazy. It is because I am separated
from the rest of my department by about 10,000 miles.You see, my family and I have had the opportunity recently to move
to beautiful... Continue Reading
I was playing around with the power and sample size graphs
in Minitab recently, and I noticed something interesting. Power,
for the uninitiated, is usually described as the likelihood that

It had been a month since my last visit. My doctor

prescribed him a P chart to monitor his wait times. I was anxious
to find out how both had worked.“Ah there he is,” said my doctor as he entered the... Continue Reading
So I’m in
my doctor’s office the other day and he tells me my “LDL” is
“What’s an LDL?” I asked.
“I’m glad you asked,” he said. “You see, LDL is the bad cholesterol
and you want it to be low.”
“So there’s a good cholesterol?” I asked.
“Yes, it’s called HDL, and yours should be higher.”“Oh, so the HDL should be higher than the LDL? Kind of like how the
UCL is higher than the LCL... Continue Reading
So I’m standing at my desk last Tuesday, when my legs suddenly
turn to Jell-O. Then I notice the overhead lights gently waving.
Soon folks are popping out of their offices with quizzical,
sometimes queasy expressions. A few phone calls and Internet
searches confirm that we have just experienced a very rare, East
Coast earthquake. One centered in Virginia but felt from Georgia to
Maine. Wow.We were... Continue Reading

Development department here at Minitab. Have you ever clicked
