How do you calculate proportional stratified random sampling?
- Proportionate Stratified Random Sampling: In this approach, each stratum sample size is directly proportional to the population size of the entire population of strata. That means each strata sample has the same sampling fraction. Proportionate Stratified Random Sampling Formula: nh = ( Nh / N ) * n. nh= Sample size for hth stratum.
How many age groups are there in a stratified random sample?
- So, you decide to gather a stratified random sample with a sample size of 5,000 and the following five age strata: Silent Generation, Baby Boomers, Generation X, Millennials, and Generation Z.
