>implying the probability of hitting a specific point on a normal distribution isn't 0

What?

Don't worry, that's illegal.

KurzweilAI is a news aggregator. It's not even run by Ray personally.

Your wording is confusing, especially when it comes to "number of times each group picked a certain choice".

If your choices are A, B, and C, do you mean comparing the number of times each group picked A, or the number of times each group picked A, B, and C?

You'll need contingency table analysis in either case, but the first case can be handled with Fisher's exact test which is much cleaner.

As for doing it in SPSS, contingency table analysis is complicated and I haven't had a working SPSS license in a year so I don't remember.

It amazes me how many people cannot into R.

As I understand it, the courses themselves will be free but you'll need to pay for the certification if you qualify for it at the end.

Animal behavior doesn't necessarily have much to do with neurobiology. I had to take one as part of a distribution requirement, and it was about 1/3 game theory, 1/3 evolution, and 1/3 derp.

>For a modest fee, and as determined by the edX board, MIT and Harvard, credentials will be granted only to students who earn them by demonstrating mastery of the material of a subject.

"Modest fee" is the only information so far.

In the fall.

I'm excited, especially after finishing Stanford's Game Theory course this Spring.

But that's wrong. Vaccination is an example of human enhancement that is literally practiced on an everyday basis.

>analyzing data with anything other than R

Stop getting trolled. Stop it. Sage, hide, and report only.

Actually, a rabbit kidney has been successfully removed, vitrified, revived, replaced, and restarted with successful resumption of function. It hasn't been done in a human yet, but proof of concept has been accomplished. The brain is, of course, another story entirely.

Warning: Game Theory requires an understanding of Bayesian reasoning despite not listing it under prerequisites.

I'm pretty sure Khan does a very similar problem. It's one of the optimization videos.

It's completely arbitrary based upon what percentage of the class you want to pass/get As/whatever other parameters you may have.

Making inferences about large populations using small subsets thereof.

People aren't aware that they can learn medicine by taking books out of a library, and think that somehow doctors gained superpowers from some medical institution that nobody else can access.

The problem is that it's really, really difficult to sneak cadavers out of the cemetery these days.

Hard to say. If you have extra money, it seems like a reliable way of getting facetime with leaders and up-and-comers in various tech fields. If you don't, it's probably not worth going into debt over.
