Suppose you want to figure out what to do with your degree in psychology.

Question

You ask some fellow students from your psychology program who recently graduated to find out what they are doing with their degree and how much it pays.
What type of sampling is this? What are the limitations of this sampling approach?

Answer 1

Biased. First of all, are you dealing with bachelors, masters or doctorate levels? Second, they probably do not represent the total population of degree graduates, but only those in your institution, which may or may not be a good representation of the population.
