# Accuracy Pet Peeve of the Day: You Can’t Give 110 Percent

Okay, seriously people.  One hundred percent means the whole thing.  Everything.  All of it.  Nothing left.

If you are asking for someone to give 110 percent, you are asking something mathematically impossible.

(Well, maybe you could use it as a description of what happens when people juice up on drugs.  “Use steroids!  They’ll give you 110 percent of your normal human ability!”  But that means if you are asking for 110 percent, you are asking your employees / students / fitness trainees to use drugs.)

A friend of mine told me that because I snark about this every time I hear it, I have successfully ruined an entire set of fitness videos for her.  To which I say: You’re welcome.  Sometimes we must sacrifice blithe entertainment for proper mathematics.  It’s the right thing to do.

# Fun With Statistics: Geico

I like to use the Geico commercials as an illustrative example for my math students about how easy it is to make statistics say what you want. Geico claims in its commercials (in many different variations) that people who switch to them save an average of 15 percent on their car insurance.

# Oh, Rick Santorum, You Are an Idiot

Last night while I was driving, I had NPR on and was listening to the coverage of the RNC, which basically consisted of live audio of the speeches.

And I kept doing that thing where I wave my hands around helplessly and mouth, “What?  WHAT?”  (It’s a good thing I didn’t crash into anything.)
