Worked Out Examples

In the following examples, we list the exact key sequence used to find the answer.  We list the keys by the main symbol on the key.  In parentheses we include a helpful mnemonic, e.g. (ex).


A: What is the mean and standard deviation of the following list of numbers?

15      16      20      21

1: Clear Memory  2nd from the right, top row of keys 2nd row ffrom the bottom, far left (stat) The Down Arrow Key: bottom part of the big gold thing The Down Arrow Key: bottom part of the big gold thing (D-CL) The Enter Key: Row 8 Column 4.
2: Enter the data:  The Mode Key: second round bullet -- right side. The One Key: Row 7, Column 2 (1-VAR) The Enter Key: Row 8 Column 4 The One Key: Row 7, Column 2 The Five Key: Row 6, Column 3 The Down Arrow Key: bottom part of the big gold thing     The Down Arrow Key: bottom part of the big gold thing The One Key: Row 7, Column 2 The Six Key: Row 6, Column 4 The Down Arrow Key: bottom part of the big gold thing The Down Arrow Key: bottom part of the big gold thing The Two Key: Row 7, Column 3 The Zero Key: Row 8, Column 2 The Down Arrow Key: bottom part of the big gold thing The Down Arrow Key: bottom part of the big gold thing  The Two Key: Row 7, Column 3 The One Key: Row 7, Column 2 The Down Arrow Key: bottom part of the big gold thing The Down Arrow Key: bottom part of the big gold thing

3: Compute the slope of the regression line  The Second Key: Upper Right Tan Bullet The Data Key: Row 2 Column 5 The Right Arrow Key: right side of the big gold thing. (b)
4: Compute the y-intercept of the regression line  The Second Key: Upper Right Tan Bullet The Data Key: Row 2 Column 5 (a)
5: Compute the correlation  The Second Key: Upper Right Tan Bullet The Data Key: Row 2 Column 5 The Right Arrow Key: right side of the big gold thing. The Right Arrow Key: right side of the big gold thing. (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.

C: Find 10C6 and 9P5.
1: Compute 10C6  The One Key: Row 7, Column 2 The Zero Key: Row 8, Column 2 The Math Key: Row 1 Column 4 The Math Key: Row 1 Column 4 The Math Key: Row 1 Column 4 The Math Key: Row 1 Column 4 The Right Arrow Key: right side of the big gold thing. (1 nCr) The Enter Key: Row 8 Column 4 Has an equals sign on it. The Six Key: Row 6, Column 4 The Enter Key: Row 8 Column 4 Has an equals sign on it.
2: Compute 9P5  The Nine Key: Row 5, Column 4 The Math Key: Row 1 Column 4 The Math Key: Row 1 Column 4 The Math Key: Row 1 Column 4 The Math Key: Row 1 Column 4 (0 nPr) The Enter Key: Row 8 Column 4 Has an equals sign on it. The Five Key: Row 6, Column 3 The Enter Key: Row 8 Column 4 Has an equals sign on it.
