Just the Stats, Man!
This is a quiz question from my Introduction to Statistics class:
“You and your roommate are arguing about whose turn it is to clean the apartment. Your roommate suggests that you settle this by tossing a coin and takes one out of a locked box he has on the shelf. Suspecting that the coin might not be fair, you decide to test it first. You toss the coin 80 times, thinking to yourself that if, indeed, the coin is fair, you should get around 40 heads. Instead you get 48 heads. You are puzzled. You are not sure whether getting 48 heads out of 80 is enough evidence to conclude that the coin is unbalanced, or whether this a result that could have happened just by chance when the coin is fair.
Statistics can help you answer this question.”
I have a few questions of my own:
- Why would I flip a coin 80 times?
- Why would I ever agree to live with a lazy, paranoid slob?
- And how many people have gone insane trying to answer questions like this one?

First Day of Summer School - and - Two Surprises
A few months ago, I started taking online courses at UMUC (University of Maryland University College) to earn a degree in Healthcare Systems Management. Today marks the beginning of the summer term, and I’m taking two classes: Introduction to Research and Introduction to Statistics. I kicked butt last term (4.0 GPA), so I shouldn’t be anxious.
I’m anxious anyway!
I just spent three hours getting in the term’s first round of study. Instead of reaching for one of my headphone sets to listen to music in the bedroom like I usually do, I went into the living room to study, and used my iPod as a music source instead of my phone. Not only was studying very productive, but I also had two pleasant surprises:
- I played my iPod’s music through our stereo, and quickly realized that I forgot what it feels like to FEEL BASS. You feel it all over your body. It is a very good feeling.
- My iPod’s song list (over 2,000 titles) hasn’t been updated in many months because my phone is my main music source. I shuffled the playlist and listened to rock, hip-hop, R&B, classical, jazz, reggae, and Latin tunes that I haven’t heard in a long time. Earth, Wind and Fire, Tito Puente, Rush, Mozart, Black Star, The Police, Kool and The Gang, Jay-Z, Beenie Man, Monica, The Roots, David Bowie, Prince, Red Hot Chili Peppers, you name it, you get the idea.
That’s it….The sun is out today, too! It’s time to run an errand or three!
