Problem with the Standard deviation calculation

[adrianT]

Hi

I am having a problem with the calculation of the standard deviation in labview.

Attached is a sample output of my program in calculating the standard deviation of a group of numbers. 

SD == Standard deviation

Thank you.

You have to be a bit more specific.

Maybe you should give an example for your "group of numbers". We cannot tell from the standard deviation result alone if it is right or wrong.

How do you calculate the standard deviation?

It would be better if you could attach your VI.

Okay

Here is a group of num bers for time =0.1 second  for position.

8.17,7.98,10.26,8.05,7.95. (x position)

Tha standard deviation is calculated by the subvi Calcs.vi (attached)

The given number result in a standard deviation of 0.997532 using your VI, which seems right. Do you expect something else?

So what is the problem? 🙂
