Knowledge Check - Multiple Choice and Multiple Select

The current plan is to interview 250 respondents, but you are considering doubling the sample size. What will happen to the accuracy and representativeness if you do?

  1. ACCURACY:

    1. *Increases

      @Correct, because Accuracy is determined by the sample SIZE. You are increasing the sample size, so the accuracy increases.

    2. Stays the same

      @Incorrect, because Accuracy is determined by the sample SIZE. You are increasing the sample size, so the accuracy increases.

    3. Decreases

      @Incorrect, because Accuracy is determined by the sample SIZE. You are increasing the sample size, so the accuracy increases.

    4. Not enough information to determine

      @Incorrect, because Accuracy is determined by the sample SIZE. You are increasing the sample size, so the accuracy increases.

  2. REPRESENTATIVENESS:

    1. Increases

      @Incorrect, because the Representativeness is determined by the sampling METHOD. You didn’t change the Sampling Method. Mall-intercept is still a Non-Probability Sample, so the representativeness didn’t change.

    2. *Stays the same

      @Correct, because the Representativeness is determined by the sampling METHOD. You didn’t change the Sampling Method. Mall-intercept is still a Non-Probability Sample, so the representativeness didn’t change.

    3. Decreases

      @Incorrect, because the Representativeness is determined by the sampling METHOD. Mall-intercept is still a Non-Probability Sample, so the representativeness didn’t change.

    4. Not enough information to determine

      @Incorrect, there is actually enough information. We know that the Representativeness is determined by the sampling METHOD. You didn’t change the Sampling Method. Mall-intercept is still a Non-Probability Sample, so the representativeness didn’t change.
