You would like to start a club for psychology majors on campus, and you are interested to find out what proportion of psychology
Natalija [7]

From the sample used to find out what psychology majors would join the club and if it is biased, we can say that;

<u><em>- Yes, the sampling method is biased. </em></u>

<u><em>- The likely direction of the bias is because you only asked 5 people which </em></u>

<u><em>is  not a significant percentage of those offering psychology majors and as </em></u>

<u><em>such the 4 out of 5 gotten is likely going to be an over estimation of those </em></u>

<u><em>who are willing to pay to join this club.</em></u>

We are told that;

  • You want to start a club.
  • This club is for psychology majors.
  • You want to find the proportion of those in the psychology majors that will join this club you want to organize.

  • Now, out of all the students offering psychology majors, you only asked 5 of them if they will be interested. Since 4 out of the 5 are interested and you want to use that to form a basis of the proportion of those interested , it would lead to <em>sampling bias</em> since the population is not adequately represented.

Therefore, this would lead to sampling bias and thus the sample is biased.
