A sample is said to be representative if the selection made form have population is free of bias. Evaluating the selection criteria listed above :

  • Sample 1 will not likely be representative as students who do not belong to either a sorority or fraternity are automatically exempted from the selection.

  • Sample 2 will not likely be representative because not all students play a varsity sport, hence students who do not play a varsity sport won't have a chance of being selected.

  • Sample 3 is a convenience sampling technique, they often exhibit sampling bias hence, sample 3 is not representative of the population.

  • Sample 4 will not likely be representative as students taking other courses aside humanities have no chance of being selected.

Therefore, all the sampling methods are not representative of the population of first year student.
