The position of the graphically
represented keys can be found by moving your mouse on top of the graphic.
I am counting every row as a row, even the top keys all labeled ^. For clarity,
I will refer to the leftmost key as f1, the next as f2, all the way over to the
rightmost key f6.

Worked Out Examples
In the following examples, we list the exact
key sequence used to find the answer. We will list the keys by the main symbol
on the key. In parentheses, we will list a helpful mnemonic, e.g. we will list
ex as
(ex).
A: What is the mean and standard deviation of the following list of numbers?

5: Compute the sample standard deviation | ![]() ![]() |
You should get a mean of 18, population standard deviation of
2.549509757 and a sample standard deviation
of 2.943920289.
B: Find the linear regression line for the following table of numbers. Also find the correlation.

4: Compute the y-intercept of the regression line | ![]() ![]() ![]() ![]() |
5: Compute the correlation | ![]() ![]() ![]() ![]() |
You should get a slope of 1.6, a y-intercept of 0.5, and a
correlation of 0.992277876.
The regression line would be: y = 1.6x + 0.5.
