Question

The drama club members at Millie’s middle school are selling tickets to the school play. Millie wants to determine the average number of tickets sold. First, she surveyed the club members in her homeroom, and then she surveyed every third member of the club in her physical education class. Which sampling technique should produce a more representative sample?
Both samples should be exactly the same.
Neither sample will be representative.
The first sampling method, surveying drama club members in her homeroom, is the most representative.
The second sampling method, surveying drama club members in her physical education class, is the most representative.

Answer 1

Answer:

The first sampling method is Convenient Sampling. It is biased sampling and it is not representative of a random sample.

The second sampling method is Systematic Sampling. If this method of sampling is drawn from the population, it is an efficiently randomized sampling method.

Let us review the given answers.

1. Both samples should be exactly the same.

  INCORRECT

2. Neither sample will be representative.

  Because the second sampling method can be random, this answer is

  INCORRECT.
