Question

Please suggest a sampling method to have a sample size of 100 samples from a total of 500 students (in which: 200 Business Administration students, 150 Languages students and 150 IT students). It is required that each member have an equal chance of being selected and that the sample contains enough students from the 3 majors mentioned

Answer 1

SAMPLING METHOD

One sampling method that could be used to select a sample of 100 students from a total population of 500 students with three different majors (Business Administration, Languages, and IT) is simple random sampling. In simple random sampling, each member of the population has an equal chance of being selected for the sample.

To implement this sampling method, you could follow these steps:

• List all 500 students in a table, including their major (Business Administration, Languages, or IT).

• Assign a unique number to each student (e.g. 1 to 500).

• Use a random number generator or a table of random numbers to select 100 numbers between 1 and 500. These numbers will correspond to the students who are selected for the sample.

• Check the list of students to see which students have been selected based on the numbers that were generated. These students will be included in the sample.

This sampling method will ensure that each student has an equal chance of being selected for the sample, and it will also ensure that the sample contains enough students from each major.
