Lies, Dmn Lies & Statistics!

[rogerrog]

Hi all,

I need to carry out some analysis at work, looking at telephone calls coming in to the office. The problem is that I don't know much about statistics (e.g. how to calculate the sample size I'll need, or how to give a percentage confidence in my results etc). I'm wondering if anyone can point me in the direction of a decent guide for newbies?

I'm fine with general arithmetic and am reasonable with Excel (although not up to the standard of many learned people on here)!

Apologies if this is slightly OT. I've spent some frustrating time Googling - the only sites I've found so far give me the fear, to be honest - they assume too much existing knowledge.

I'd be very grateful for any help.

Many thanks,
Rogerrog.

Good for basic stuff and really walks you through the calculations.

(Hope this isn't one that gave you the fear!)

Oh top drawer, thanks a million slomobonobo... I've had a look through some of the introductory sections and this looks perfect for novices like me.

Cheers!
