I want to protest!
lol just now tuition right, i did some standard deviation practices.
GOSH!!!!!!!!!!!!
THE STEPS ARE NEVER ENDING
U find the frequency times the data, then find mean, then find data minus mean, then find square of data minus mean, then use frequency times the square of data minus mean, then divide by the sum of frequency......
AND IT GOES ON AND ON AND ON AND ON........
Crap la!
