Once you entered all the values, just use the statistical functions as you explained. However, in other models this does not work, and doing that will enter the value 30 once. In some models you can enter repeated values, for example 3×10 DT will enter don’t remember if the value 3 10 times or the value 10 3 times. To enter the data, just type the value and press the data enter key (named DATA or DT, which typically is the M+ or Min key without shift). Now, if you press “n” you will get 0 and with “Xbar” you will get an error. To do that use “Scl” (typically SHIFT + AC). The first thing you want to do is to clear the statistical memory. When the function name is printed in blue, you use it pressing the key without shift. When the function is not printed in blue but it is in a blue brecket, you must press “SHIFT” first. Once you are in the SD mode (probably you will see SD somewhere in the screen), look for the keys marked with blue. I don’t think that it’s your case, but in the oldest models the mode is selected with a sliding switch. The name of the normal mode is ussualy “COMP”. To return to the normal mode you do the same. If, for example, SD is the mode number 2, you must press “MODE” and then “2”. In the newer ones by pressing the key “MODE” several times you go through a menu of modes. In the older calculators there is table of modes printed near the screen. You have to press that key and then a number. To switch modes, typically there is a “MODE” key. I’ve never used that model, but the CASIOs are all more or less the same.
