Hello!
please tell me how to calculate probability between two mean values 0.33
(with std dev 0.22) and 0.56 (with std dev 0.41).

Rijan

Hi,

Can you give us a little more information as to what you are trying to
achieve?

Thanks,

Dear David,

Thanks. I want to know whether the two mean values are singnificantly
different or not.

Rijan -

The phrase "significantly different" usually applies to statistical
inference. Consult a book. You'll need to make assumptions about the
underlying population distributions, and you'll need to know the sample
sizes of the random samples.

If you want Excel to do the calculations for you, one way is to start with
the data for the two random samples in columns on a worksheet, choose Tools
| Data Analysis, and pick the appropriate t-test.
