Answer to question 6
a. In case of Simple Random Sampling, each of the six apartments out of hundred apartments
will be assigned with a number between 1 and 100, after which 6 of those numbers would be
randomly chosen2.
b. In terms of the cluster sampling, the statistician divides the whole population into clusters and
each clustered would be assigned with equal probability. The total population size of 100
apartments will be separated into groups by assigning the same average members for each group.
c. In terms of stratified sampling, a sample is chosen from the population in such a way that
selected sample contains the characteristics of the population. Here, the population of 100
apartments can be stratified into subgroups by number of rooms available in the room, like,
single and duplex flat.
