Hello all, I am having a bit of difficulty with making a spreadsheet
that
entails the use of calculating various statistical formulas. I have
searched
the net on this topic and have only managed to find exactly what I have
found
help on in the help section of Excel. OUt of the formulas I needed,
the
following list as of now is what I do not know how to enter into excel.
I do
know the formulas as how you would write them out on paper and that is
included with the statistical terms. If anyone knows of a website that
can
explain in detail how to enter these as well as other formulas into
excel, It
would be much appreciated. I will be needing to add more formulas on a
weekly
basis starting next week when I deal with the introduction to
probability in
statistics. Here are the formulas I need to know how to enter into
excel:

"Midpoint" which is (Lower class limit) + (Upper class limit)/2

"Relative Frequency" Which is Class Frequency/Sample Size (Also how
to get the class frequency and sample size in excel would also be
appreciated.)

"Weighted Mean" which is The sum of (x*w)/n

"Mean for Grouped Data" which is the sum of (x*f)/n

"Sample Standard Deviation for Grouped Data" which is the Square
root of the
sum of (x-xbar)^2*f/n-1

"Chebychev's Theorem" which is The portion of any data set lying
within K
standard Deviation (k1) of the mean is at least :
(whole number 1) - 1/k^2 .

Thanks in advance to anyone that can help.
