Just something heard on the radio today, made me smile

As usual, a super busy week followed by a super busy weekend. I can now add window painter and go'er up ladder to my cv! Things are looking up for a change but I'm not going to talk about them for fear of jinxing things.

It got me again, not escaping characters in my rss feed. I knew what was happening as soon as I saw the error this time though which helped, I still forgot to put the extra code in to start with though Also de-bugging was made harder because i.e. refused to admit that there was a new file there, instead insisting on complaining about the old error making me think it wasn't fixed after all.

Standard Deviation

Submitted by BinksUK on Sun, 04/23/2006 - 08:29

Calculate the mean of the batch

For each number in the batch work out the numerical difference (number - mean)

Square each difference

Add together the entire list of squared differences

Devide your total by the number of values in the batch

Work out the square root of this total

This gives you the standard deviation
