Hello,
Here is a detailed exemple. Hope it helps.
Some comments on the various variables (should the information be needed. If not need, please skip it.)
1.All you have to do is follow the instructions key stroke for key stoke, but enter
your own data.
2. If a number is repeated 3 times like the number 55, you can enter it 3 times or use the shortcut in the exemple
55 [2nd][FREQ]3 [Sigma+].
3.If
you make a mistake and enter the wrong number, use the [Sigma-] key to
remove it. That is similar to what a cashier does when an item is
entered twice: it is entered a third time but with minus sign.
4. Every
time an item is entered, the display shows the total number of items so
far. When it is finished the cashier press the key that sums up the
prices to get the total. This is the role of the [2nd][Sigma X] key
combination.
5. The average number of the data is obtained by the
[2nd][x bar] combination. The last two key combinations display the two
type of deviations.
Check the theory you have been taught and try
again. If that is not the type of statistics you were supposed to do,
then give more information.
