[Phys-l] Basic statistics

[Ludwik Kowalski <kowalskil@mail.montclair.edu>]

I do not recall what motivated me. But I wrote a short essay on basic 
statistics. Retired teachers like teaching. In any case, this essay is 
now at:

Comments will be appreciated, especially if something is wrong. I will 
be happy to correct mistake or add something that should be added. Keep 
in mind, however, that a short essay is not a textbook.
P.S.
The Greek symbol delta (capital), in my htnl code, is Δ . And it 
does the job, at least with my browser. But the code µ that was 
expected to produce the Greek letter mu did not work. I do not know 
why. So I just typed mu. Little help with html coding for Greek symbols 
will be appreciated, preferably in the form of  examples that are known 
to work on most browsers.

Even if you do not care about my essay, do not miss the URL for a great 
statistical calculator that can be used over the Internet. It is much 
more convenient than z and t distributions tables. Try it at:
