Туpes: i) Equal Allocation - this is used when you want to obtain an equal number of samples from each stratum. Divide the sample size by the number of strata. :- where n is the sample size, k is the number of strata and ng is the sample size from each stratum. Example: Suppose there are 3000 DLSMHSI students and you only need a sample of n =100O. If there are k =8 identified strata (CM, CN, CRS, CHS, CP, CMIT, CMLS, SHS), then ng = implying that there are [ex1] samples to be taken from each college and department. What if we want a sample of n = 800 only? ng = implying that there are [ex2] samples to be taken from each college and department.
