Re: Random Variables

Hi;

Okay! Very good.

Nice example, not only informative but mouth watering also.

In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

All good.  smile

You might consider a link from Variance on the third page to your Standard Deviation and Variance page.

Re: Random Variables

Hi MathsIsFun,

They're good!
You may consider adding a few lines about central moments, and tell that variance is one of those.
