Cluster Sampling Method

Example : The Student Council wants to stand an intramural sports programs. The first step is to determine which sports the 1000 students in grade 9-12 would like to have in the intramural. Each of the five memebers of the student council sets out to collect data.

General Characteristic: Jill is a grade 11 student. She decides to ask 100 grade 11 students which sports they would like to have in the programs.

Strengths: The strength of the sample is that size is good and the data is easy to obtain.

Weaknesses: The weaknesses that the sample gives that not all the students have equal chance of being selected and not all grades are represented.

Biased: The sample is biased because Jill's sampling method does not show the entire population and not all students are not included in her asking.
