After you finish entering the data
Press [SHIFT] [9] (sigma n-1) to get sample standard deviation
Press [SHIFT][8] (sigma n] for the population standard deviation
Press [SHIFT] [7] (xbar) for the mean
Press [SHIFT] [6] (n) for the number of data entries
Press [SHIFT] [5] (capital sigma x) for the sum of values
Press [SHIFT] [4] (capital sigma x to y) for the sum of squares of the values
For additional information you might consider taking a look at the calculator manual.

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.

Is there a PDF with the Statistical procedures for this product? I bought my Casio FX-115 used (second hand). No instructions. I need help using the Statistical functions for my Stats classes:
Correlation Coefficient
Standard Deviation/Variance
Chi-Square
x-x(bar) summations
HELP!
