Question

How can you obtain a random sample of 60 students from MQBS student who are enrolled in BCom with a Major in Marketing in Session 1, 2020? (hint: think about the relationship between population and a random sample).

Answer 1

To create a simple random sample, there are six steps: (a) defining the population; (b) choosing your sample size; (c) listing the population; (d) assigning numbers to the units; (e) finding random numbers; and (f) selecting your sample.

The population is the students at the MQBS of BCom with major in Marketing of session 1,2020. The population is expressed as N. Since we are interested in all of the MQBS students we can say that our sampling frame is all N students.

A sample of size 60 is needed.

To select a sample of 60students, we need to identify all N of MQBS students. We may need students record for that to get list of all MQBS students.

We now need to assign a consecutive number from 1 to N, next to each of the students.

Next, we need a list of random numbers before we can select the sample of 60 students from the total list of N students. These random numbers can either be found using random number tables or a computer program that generates these numbers for you.

Finally, we select which of the N students will be invited to take part in the research. In this case, this would mean selecting 60 random numbers from the random number table. Imagine the first three numbers from the random number table were:

0011

0056

0009

Select 11 th, 56th,9th student.

and so on... until we get 60 members in our sample.
