Entering data
one variable
To get into stat mode (SD1), press The Mode Key: Row 1, Column 6 The Times Key: Row 7, Column 4. Enter the first value and press The x-th root key: Row 5, Column 6 (You will see DT in blue under the key, DT is short for DATA). Enter the second value and press The x-th root key: Row 5, Column 6. Continue in this fashion until the end of the list.  
two variables
To get into stat mode (LR1), press The Mode Key: Row 1, Column 6 The Division Key: Row 7, Column 5. (If you forget this, the top of the calculator has it listed). Enter the first x-value. Press The Shift Key: Row 1, Column 1 The Left Parenthesis Key: Row 5, Column 3 (there is a comma on top). Enter the first y-value and then The x-th root key: Row 5, Column 6.  Continue in this fashion for all the ordered pairs.

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?

15      16      20      21

1: Clear Memory  The Shift Key: Row 1, Column 1 The Delete Key: Row 6, Column 4
2: Enter Data  The Mode Key: Row 1, Column 6 The Times Key: Row 7, Column 4 (SD1)  The One Key: Row 8, Column 1 The Five Key: Row 7, Column 2 The x-th root key: Row 5, Column 6 The One Key: Row 8, Column 1 The Six Key: Row 7, Column 3 The x-th root key: Row 5, Column 6 The Two Key: Row 8, Column 2 The Zero Key: Row 9, Column 1 The x-th root key: Row 5, Column 6 The Two Key: Row 8, Column 2 The One Key: Row 8, Column 1 The x-th root key: Row 5, Column 6
3: Compute the mean   The Shift Key: Row 1, Column 1 The One Key: Row 8, Column 1
4: Compute the standard deviation (population)   The Shift Key: Row 1, Column 1 The Two Key: Row 8, Column 2 (xsn)
5: Compute the standard deviation (sample)  The Shift Key: Row 1, Column 1 The Three Key: Row 8, Column 3 (xsn-1)


    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.

x 1 2 3 4
y 2 4 5 7

1: Clear Memory The Shift Key: Row 1, Column 1 The Delete Key: Row 6, Column 4
2: Enter Data  The Mode Key: Row 1, Column 6 The Division Key: Row 7, Column 5 (LR1) The One Key: Row 8, Column 1 The Shift Key: Row 1, Column 1 The Left Parenthesis Key: Row 5, Column 3 The Two Key: Row 8, Column 2 The x-th root key: Row 5, Column 6 The Two Key: Row 8, Column 2 The Shift Key: Row 1, Column 1 The Left Parenthesis Key: Row 5, Column 3 The x-th root key: Row 5, Column 6 The Three Key: Row 8, Column 3 The Shift Key: Row 1, Column 1 The Left Parenthesis Key: Row 5, Column 3 The Five Key: Row 7, Column 2 The x-th root key: Row 5, Column 6 The Four Key: Row 7, Column 1 The Shift Key: Row 1, Column 1 The Left Parenthesis Key: Row 5, Column 3 The Seven Key: Row 6, Column 1 The x-th root key: Row 5, Column 6  
3: Compute the slope of the regression line   The Shift Key: Row 1, Column 1 The Eight Key: Row 6, Column 2 (B)
4: Compute the y-intercept of the regression line  The Shift Key: Row 1, Column 1 The Seven Key: Row 6, Column 1 (A)
5: Compute the correlation  The Shift Key: Row 1, Column 1 The Nine Key: Row 6, Column 3 (r)


    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.
