How do you calculate disproportionate stratified sampling?
Proportionate and Disproportionate Stratification
For example, if the researcher wanted a sample of 50,000 graduates using age range, the proportionate stratified random sample will be obtained using this formula: (sample size/population size) × stratum size.
What is disproportionate stratified sampling?
an approach to stratified sampling in which the size of the sample from each stratum or level is not in proportion to the size of that stratum or level in the total population.
How do you calculate stratified sample?
To implement stratified sampling, first find the total number of members in the population, and then the number of members of each stratum. For each stratum, divide the number of members by the total number in the entire population to get the percentage of the population represented by that stratum.
What is the formula of random sampling?
The Formula of Random Sampling
(N-n/N-(n-1)). Here P is a probability, n is the sample size, and N represents the population. Now if one cancels 1-(N-n/n), it will provide P = n/N. Moreover, the chance of a sample getting selected more than once is needed: P = 1-(1-(1/N)) n.
