Using your calculator to find summary stats (sample mean, sample standard deviation, etc)

Entering data into a list:

1. From the home screen, choose option 2 STAT by either pressing the “2” button or arrowing over to it and pressing the EXE button.
2. Enter in the data by typing each observation and pressing EXE.
3. You can delete an entry by pressing the “DEL” button.

Computing the Summary Statistics after entering the data in a list:

1. From the list screen, you can press the “F2” button (the tab on the screen shows CALC, so this takes you to the calculations options).
2. The tabs at the bottom left of the screen should now say “1VAR” and “2VAR”. Press “F1” to choose 1VAR.
3. The screen should now show the summary stats. Sigmas (σ) display a bit different on the Casios; the tail is long and goes off to the upper right:
   So the population standard deviation looks like  and sample standard deviation is .

Chapter 5 Binomial Distribution

Computing Binomial Coefficients

1. Type the top number, then press OPTN, F6 (arrow for more), F3 (PROB), F3 (nCr), bottom number, EXE.

Checking Binomial Distribution (for P(X=x) only, does not work for less than or greater than)

1. Get to Stat mode by MENU, 2: STAT.
2. Then hit F5 (DIST), F5 (BINM), then Bpd (I think this is F1).
3. Set the data to Variable by pressing F2.
4. Type in your values for , Numtrial (), and , then EXE.

Chapter 6 Normal Distribution

Checking percentage of observations between two values

1. Press MENU and choose option 2 STAT, EXE.
2. Press F5 (DIST), F1 (NORM), F2 (Ncd).
3. Type in lower, upper, standard deviation, and mean, then go to Execute and press EXE.
