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.
