What is the FPC
1-(n/N)
Critical value for t (tx)
2.05
Sample Variance Calculation
V(Ybar)
V(Ybar,str)
VSRS(Phat,SRS)
What is the sample size calculation for Neyman
Sample size calculation to compare between strata?
MSE
V(σhat)
Bias(σhat) Equation
How are Bias and Var related to MSE
Bias^2 + Var
CVhat(Ybar)
Estimate shat
This is the range of the data divided by 4
How do you calculate e (Margin of Error)
It is the critical value (z) multiplied by the standard error
Proportional sample size calculation
(Nh/N) * n
SSW
sum(Yi - Mean of strata)^2
SSB
sum(Yi - Overall Mean)^2
SSTO
SSW + SSB
