Standard diviation


To use one-variable statistics the simple way, go into the Data Editor and enter your data into a column. Press F5 to calculate. Select 1-var stats. I believe you've got this much of it. Then, in the first box, enter the name from the header of the column you entered the data into. For "Use Freq and Categories?" select NO.

When you press ENTER, you should see a screen with the one-variable statistics.

To get the standard deviation the easier way, simply put the data into a llist and then use the stdDev function (or the stdDevPop function for the population standard deviation) function on it. For example:

stdDev({1,2,3}) gives 1.
