Hi;

Okay! Very good.

Nice example, not only informative but mouth watering also.

hi MathsIsFun,

All good.

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

Hi MathsIsFun,

They're good!

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