Stratified Random Sampling
    The first thing that has been selected considering the Probability is commonly known as the Stratified Random Sampling. This is a method where a certain part of the population is divided into relatively smaller sub-groups and her hence called strata (Nguyen et al. 2018). This method is also known as stratification that comes from the word “strata” where is division is done based on shared characteristics. It is in turn divided based on characteristic facets such as education attained or income. 
    It can be explained through an example where the population tends to be 1000. Consequently, the subgroups will be created as follows:
Male undergraduates = 45% of the population or 650 students 
Female undergraduates = 25% of the population or 250 students so on and so forth
The advantages, as well as the disadvantages of the stratified random sampling, are discussed as follows:

    · The population is scrutinized effectively therefore the sampling provides accurate coverage concerning...
