RE: [tips] A Cute Way To Teach The Central Limit Theorem

2014-01-24 Thread rfro...@jbu.edu 
Although Paul can't quibble, I have to quibble a bit (although I can't quibble 
with its being described as cute - its cuteness is unassailable).

As someone who knows what the Central Limit Theorem is and its relevance for 
inferential statistics, I can follow it and understand what it is 
communicating. Trying to take the point of view of an intro student who doesn't 
know the relevance of the CLT or what it is, I have my doubts that it would 
mean much to them. One thing that I think would be confusing is, in the process 
of trying to make something that is largely theoretical come to life, they have 
the animated biological field worker decide that it would be too difficult to 
measure all of the rabbits in the population so, instead he is going to collect 
numerous samples of a particular size and then take the average of those 
samples to estimate the population average. Doing that would nullify the 
advantage of knowing the Central Limit Theorem. I think a student would 
reasonably ask, "how is it easier to take numerous samples and calculate a mean 
instead of just measuring all of the animals in the population?" And then they 
will wonder why, in the studies they read, researchers appear to be basing 
their results on only one sample.

Thanks for sharing this. While I can quibble (I can always quibble), I think it 
is very good.

Re: [tips] A Cute Way To Teach The Central Limit Theorem

2014-01-24 Thread John Kulig 

I liked the dragons better than the rabbits. I would have explained it to a 
class by having a random sample of 2 dragons from the bimodal and creating a 
sample space with 4 possibilities: Short/Short, Short/Long, Long/Short, and 
Long/Long. There are twice as many ways to get a medium average. Cool. 

Iditarod? Does Mike P have snow all the way down there in New York?
