Hello

I have a problem, and seeing as I don't know a lot about stats I guess I need some help!

I have to answer the question:
With what confidence can i say that this sample came from this individual?!

Basically, I tested 11 people, they typed 'i only read' 20 times each, and i recorded latency and dwell of keystrokes (latency being length of time between successive key strokes and dwell being the amount of time a key is held down for.)

I have put all the loggged information onto the attached spreadsheet, and have calculated the mean and standard deviation. But now i don't know wher to go, so any suggestions on statistical methods regarding how i measure confidence in the sample would be great full.

The final aim of the project is to try and get a computer to tell who is at the terminal by just looking at there keystrokes.


I have been told i should be able to produce a matrix of confidence levels......but i have no idea where to start?!?

Hopefully someone can help me.

If you need more info leave a message or email me on [email protected] and i'll talk directly to you.

Cheers in advance for any advice

Andy
