Question:A company wishes to carry out a national survey of adults'reading habits.To reduce travelling costs,the country was divided into constituencies.A sample of 50 constituencies was selected at random.With each of these constituencies,5 polling districts were selected,again using random techniques.Interviewers will visit a random selection of 30 people on the electoral register of each district selected.
 
What sampling method is the company using?
 
A.Stratified
 
B.Systematic
 
C.Multi-stage
 
D.Simple random
 
The correct answer is:C
 
The sample is selected in stages,at first selecting not individuals but constituencies.
 
Multi-stage sampling is the correct answer as this method involves dividing the population into a number of sub-populations and then selecting a small sample of these sub-populations at random.Each sub-population is then divided further.
 
Stratified sampling involves dividing the population into strata and then taking a random sample from each stratum.
 
Random sampling is where every member of the population has an equal chance of being selected and systematic where every nth item after a random start is selected.
