20. PROPORTIONAL QUOTA SAMPLING

Question 1

1. What sampling method does Proportional Quota Sampling share principle with?

Answer 1

• Stratified Random Sampling

Question 2

2. How do we select the Sample for the Proportional Quota Sampling Method?

Answer 2

• the sample is selected on a weighted manner
• this is based on the predefined Strata
• the strata are the distinct population subgroups

Question 3

3. What can be said about the Strata we find in the Proportional Quota Sampling?

Answer 3

• the Strata are filled by non-random sampling
• this sampling can be systematic

Question 4

4. Does this example make sense?

Answer 4

• yes

Question 5

5. What are the 5 steps of the Proportional Quota Sampling Procedure?

Answer 5

1. Identify the Source Population
2. Set up the Sampling Frame
3. Decide on the Sample Size
4. Decide on the pre-defined Population Strata
5. Select all the individuals to fill the Strata
   (these individuals are non-randomly selected)

Question 6

6. What are the 2 advantages of the Proportional Quota Sampling?

Answer 6

1. IT IS AN ACCEPTABLE AND ALTERNATIVE APPROACH
   - it is more convenient
   - if for some reason we cannot make use of Stratified
   Random Sampling
2. COMPARED TO SIMPLE SYSTEMATIC SAMPLING
   - this method of sampling can ensure the original
   population structure
   - this is because it uses predefined population strata

Question 7

7. What is the one disadvantage of the Proportional Quota Sampling?

Answer 7

1. THE REPRESENTATIVENESS OF THE SAMPLE
   - may be compromised because individuals are
   selected in a non-random fashion
