Thank you Dada
can you please explain why you wrote (17-a)^2 .....
just one thing how can i figure out that standard deviation= Sum of sqare of difference and observation
i mean how you figured out that because standard deviation formula is pretty odd to this 1/n (x - mean)^2
x is sum of observation - mean
acha
ok
how can i mention you in any question as i have more question to ask Dada
