To obtain a stratified sample of student satisfaction with MyMathLab courses at South University, you would first divide the population of students into different strata or groups based on certain characteristics that may vary across the population. For example, you might consider stratifying the students based on their year of study, major, or previous experience with online courses.
Once you have identified the strata, you would select a random sample from each stratum. The size of each sample can be proportionate to the size of the stratum in the population, or you can allocate a fixed number of respondents from each stratum.
To do this, you could start by obtaining a list of all students at South University who are enrolled in MyMathLab courses. Then, you would categorize them into the appropriate strata based on the chosen characteristics. Finally, you would randomly select the desired number of students from each stratum to participate in the survey. This can be done using random number generators or by using a systematic sampling method.
On the other hand, to obtain a simple random sample of student satisfaction with MyMathLab courses at South University, you would randomly select a specific number of students from the entire population of students enrolled in those courses. This means every student in the population has an equal chance of being selected.
To achieve this, you could again start with a list of all students enrolled in MyMathLab at South University and assign each student a unique number. Then, you would use a random number generator or a similar method to randomly select the desired number of respondents from this list.
It is important to note that regardless of the sampling method used, efforts should be made to ensure that the selected sample is representative of the population of interest to obtain accurate and reliable survey results.
