SOURCE: standard deviation
Enter the first number, 1.
Hit the σ+ (Sigma+) key. ( n=1 will appear in the window)
Enter the second number, 1.
Hit the σ+ (Sigma+) key. (n=2 will appear in the window)
. . . . .
Enter the last number, 7.
Hit the σ+ (Sigma+) key. (n=7 will appear in the window)
Hit 2nd x2 (by hitting the 2nd key you are actually selecting the x-bar written above the key.) This gives you the mean.
Hit 2nd sqrt(x). This gives you the sample standard deviation which we will use in class.
Make sure you turn your calculator off and on for new data sets.

When I enter some series of data and check the descriptive statistics, every time I come to the standard deviation the calculator shows me Error 1 message.

I took statistics last semester and I don't really remember how, but after you enter your data, you press SHIFT, then STAT (on the 1 key), then I think it's under 5 (VAR), and maybe Xon-1? Eh, funny how long you remember this stuff for....
