Ti 30x Iis Calculator Manual
Then, before beginning a specific unit of the text, check to see if this includes keystrokes for that unit. Going through the keystrokes before class will help, especially if your instructor cannot include instructions for the TI-30X IIS during class. Calculator registers. Most keys have 2 functions. One appears in white on.

TI-30X IIS - Calculator Help The TI-30X IIB has the exact same keys as the TI-30X IIS. S is the solar version of the calculator and B is the battery operated version. The position of the graphically represented keys can be found by moving your mouse on top of the graphic. Turn your calculator on Press.
Clearing the memory Press (you should see STAT above the key). A menu is displayed with three choices. Press so that the word CLRDATA is underlined. Press (you should see ENTER on the key). Entering data one variable Press (you should see the word STAT above the key).
A menu is displayed with three choices. The 1-VAR option should be underlined. Press (or ENTER), then again.
If 1-VAR is not underlined, use arrow keys to underline it. Type in the first number, then press. Next the calcuIator is expecting a frequency (how many times this value occurs in your data set). 1 is the default value, so if this number occurs only once in the data set, press. However, if the number occurs more than once in the data set, type in the number of times it occurs and then hit. You should see FRQ= (frequency).
Ti-30x Iis Manual Standard Deviation
Then enter the second number from the data set. Enter the frequency of the second number and hit again. Continue until all the data has been entered. Press as your final step to signal the end of the data set. Two variables Press (you should see STAT above the key). A menu is displayed with three choices. Press once so that the word 2-VAR is underlined.
Type in the first x-value, press. Type in the corresponding y value, then. Continue until all the data has been entered.
Press as your final step to signal the end of the data set. Calculating one-variable statistics mean ( x) Press. On the top of the screen, you'll see a list of the values the calculator computes. Use to move the cursor to x (it's the second thing in the list). The mean value will be on the screen. Standard deviation for populations ( s or s n) Press. On the top of the screen, you'll see a list of the values the calculator computes.

Use to move the cursor to s x (it's the fourth thing in the list). The population standard deviation will be on the screen. Standard deviation for samples (s or s n-1) Press. On the top of the screen, you'll see a list of the values the calculator computes.
Use to move the cursor to S x (it's the third thing in the list). The sample standard deviation will be on the screen.
Calculating two-variable statistics Make sure you are still in the 2-VAR mode when you do these. R (correlation) Press.
On the top of the screen, you'll see a list of the values the calculator computes. Use to move the cursor to r (it's the tenth thing in the list). The correlation will be on the screen. Regression coefficients slope Press. On the top of the screen, you'll see a list of the values the calculator computes. Use to move the cursor to a (it's the eighth thing in the list). The slope will be on the screen.
Y-intercept Press. On the top of the screen, you'll see a list of the values the calculator computes. Use to move the cursor to b (it's the ninth thing in the list). The correlation will be on the screen. Calculating combinations and permutations Make sure you get out of the STAT mode before doing these. To get out of STAT mode, press (says EXIT STAT on top of the key). Combinations (nCr) Enter the n-value.
Press (short for PRoBability). On the top of the screen, you'll see a list of the values the calculator computes. Use to move the cursor to nCr (it's the second thing in the list). Enter the r value, then press. Permutations (nPr) Enter the n-value. Press ( short for PRoBability). On the top of the screen, you'll see a list of the values the calculator computes.
Use to move the cursor to nPr (it's the first thing in the list). Enter the r value, then press.
Turning the calculator off Press. (You should see the word OFF above the key.) 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 e x as (e x). A: What is the mean and standard deviation of the following list of numbers? 15 16 20 21 Do alt tags: The One Key is Row 8, Column 2.
