Dec 9th 2008 Standard Deviation

Today is a wonderful day. The sun is shining and nonmigratory birds are singing. We started off our beautiful math class with good ol' mental math. The questions were concerning our current unit, standard deviation. The fact of the matter is that I honestly don't understand concept of this unit. I was away yesterday due to poor health. Apparently it was a good class to miss.



The subject of today's class was based on normal distributions. We did an example pertaining to men's height in the city of Hong Kong. We learned how to use our calculaters to determine standard deviation. Mr. MAKS-SYM-CHUK showed us a good website to figure out normal distribution.
