Unit One Test

Test average = 73%

High score = 92%
Low score = 48%

Median score = 73% (weird, that it's the same as the average, hey?)

I am pleased. I know that many of you aren't, and that's cool. This was NOT a test that you should have left thinking, "Oh, I aced that one. How much easier could she have made it?"

Retests will be available after next Monday. There is one person that has to test, and you will receive the scan sheet (with answers) and your test booklet on Friday. You'll have the weekend to look it over, and we'll talk about it on Monday. After that, you may retest to your heart's desire; I will take the highest score you get.

There are two on the scan sheet that were graded incorrectly; I put the wrong answers on the key (that's why doing the analysis of seeing which questions were most wrong helps so much - if 18/20 get it wrong, then it's the question, not the test-taker...). Those are corrected on your scan sheet if you got the extra points. Also, there were two questions with answers that were ambiguous; although I thought they were clear, after seeing results and what people put, they were written badly. Those were taken out of the count.

I'll show you scores tomorrow. :)

Have a nice night - good job!

SOOOOOO... First of all, my disclaimer:
WARNING this is a question for the second week of posting, and not the third.

My question is about microeconomic problems. Ok, yes this kind of has to do with our quarter three project, but not really. I just want to know how you come up with these "microeconomic problems". Or could you define "microeconomic problems"? For example, I don't understand how drilling for the oil in the arctic is a micro and not macro economic problem.

Ok, it's me again. I have been reading through the ultimate book and I am finding that there are a lot things I don't understand. But again, this is my second question for the second week of posting and not the first. That's what I meant on my first post, that it was for the second not the third. Anyway,
Could you explain externalities to me? I just do not understand it, and I didn't understand it when Wheelen was talking about it and I just need some really good examples, or something. These definitions that you find in the book just don't do it for me.

I promise, we'll talk more about externalities when we get to supply & demand. It makes a lot more sense there.

An externality is anything that happens outside a market, but affects the market. So - the cold in my classroom. It does not have anything to do with my class, how I teach, what happens in there - but some people get soooooo deadly cold in there that they can't learn. That's an externality.

Pollution is a big one. Factories produce things, and pollution is a by-product. They don't intend to. If we shut them down because of pollution, they can't make things anymore. So the pollution affects the market by decreasing supply.

Ummm...smoking. Gov Doyle is looking for a boycott of smoking in all public places in WI. Someone else smoking affects others, whether that is the intention or not. If you smoke, I get secondhand smoke and die of cancer. My husband smokes. I hate it, because I am an ex-smoker and susceptible to smoke, plus I have asthma and it bugs my lungs. He doesn't mean for it to affect me, but it does.

Drilling for oil in the Arctic has that pollution by-product. So does acid rain. So does strip mining. So does car emissions. So does...lots of other things. So they are micro-economic, because they affect the consumer and producer more than the economy as a whole.

We'll talk more about the project next week. That will give you a full month to think about it. :)

Hey Keri!

In our Naked Economics book (i think, although i could have read it elsewhere) i remember reading about that, although to be honest with you i cant remember what page. Something about buying an SUV. You buy it because its safe, and the person sells it to you too much money. But what we dont consider is what is going to happen to the third party driving a little bug when you get an accident with an SUV. Ring a bell?? Gina and i were talking about externalities today in study hall! :-)
