Why can't you do these yourself Natasza?
To find a mean you just add up all the numbers and divide by how many there are. It is another word for average.
The others can be done either by formula or on your calculator. I expect there are stat functions on the web2 calc but I will admit that I have not looked.
Now, what in particular would you like help with?
