Daniel Sample Size Formula. If we took p 5 then the sample size would be. Z Z value eg.
This calculator will compute the sample size required for a study that uses a structural equation model SEM given the number of observed and latent variables in the model the anticipated effect size and the desired probability and statistical power levels. For a confidence level of 95 α is 005 and the critical value is 196 MOE is the margin of error p is the sample proportion and N is the population size. 2 2 1 d Z P n where n sample size Z Z statistic for a level of confidence P expected prevalence or proportion in proportion of one.
Confidence andor the level of precision which would give you 166 for a sample size.
Z Z value eg. If the population size is very large but not known exactly ie. Z 196 for 95 confidence σ SD of DEx. Ie the minimum sample size required for a significance test of the addition of a set of independent variables B to the model over and above another set of independent variables A.
