Well, at least I've been mentioned on one of my favorite blogs.
This doesn't really have anything to do with education, college, or graduate school. Maybe it does. I should be studying. That might count for something.

Starbucks Deals...
Are you a Starbucks addict? This is for you.
Do you remember when I talked about Giant Eagle Fuel Perks and gift cards? If you buy the Starbucks ones, you should go to their website and register the card. If you do, you'll get free stuff at Startucks if you tell them you're paying with a registered card.
Also, if you made it to Starbucks last Wednesday, you can get free coffee today.
Finally, please click an ad.

Mid-Term Today...
If you're in my statistics class, (Ag Ed ###,) here's what someone who went to the review session told me:
Most of the time, grouped data are considered to be ordinal. Percentages can be interval or ratio. Course grade is considered to be rank data, because it's not always the case that each grade is 10 points more than the other.
Skewness and normal is not synonymous, because you may have a bimodal polygon with 0 skewness, but its not normal.
Most measures of central tendency, variability, etc., cannot be determined from a frequency polygon, nor from grouped data, they must be determined from the raw data. But with a frequency polygon, you can see a tail better. With grouped data, you can't even tell your range, because you're not sure at what number the tail ends.
We don't need to know about z scores, nor the diff between kendall's tau b and c, nor chic squares, nor ogive curve.
Also, if you don't mind, please click an ad.

Get to Starbucks immediately...
Order a tall/small Pike Place Roast. It's free today, (Wednesday.)
That's merely being frugal. If you want to be completely cheap, you'll notice you also get a green card. This allows you a free coffee every Wednesday until May 28.
You're welcome.

Not really a post...
I'm not sure why I haven't posted in a while. I've got it down to two competing theories.
1. I'm completely overwhelmed with school, life and the goings on of Columbus, Ohio.
2. I'm really lazy and haven't thought of any good topics to talk about.
It's probably the second one.
Anyway, my class notes, (see the link on the right,) are still being updated. If you miss a class, or just want a different perspective, stop by and check them out.
Stay bamboocha,
Michael
