Question

Identify the sampling technique used (or to be used) in the following scenarios. Possible answers could be simple random, systematic random or stratified random sampling.

Answer 1

a)

This sampling technique is simple random sampling, since the students are selected at random by drawing their names from a piece of paper.

b)

Since there is a condition to select a resident (being the sixth resident of the list), this technique is classified as systematic random sampling.

c)

The 20 students were selected by using a table of random numbers without any criteria. Therefores, this is a simple random sampling technique.

d)

Since, among the 100 selected random people, there was a pre determined subgroup of 5 barangays, this is a stratified random sampling technique.

e)

Since everyone in the sample was selected at random by dwaring lots, this is a simple random sampling technique.
