Advantages and Disadvantages of Probability Sampling


  • Your ┬ásample is more likely to be representative.
    • Because all members have an equal chance of being selected, your sample is less likely to be biased.
  • The ability to generalize conclusions about the population is higher


  • Resource use (e.g. cost) can be higher to develop these types of samples.
  • Greater expertise and knowledge of the subject matter is needed to determine what type of sampling approach is most appropriate.
