Sample Surveys

9. Calculating Survey Weights

Exercise 4

Questions 1 of 2:
If you use a simple random sample design, then you do not need to use survey weights.

Select True or False.

Answer:
False – There are other adjustments that get applied in calculating survey weights. For instance, adjusting for response rate or known population information may be used to calculate survey weights for a simple random sample.

Questions 2 of 2:
What are some reasons survey weights are used? Identify which reasons for using survey weights below are true and which are false.

The reasons are:

  • Weights are unimportant except large-scale government surveys.
  • To adjust for nonresponse, especially if it differs across subpopulations.
  • To adjust for unequal selection probabilities so that estimates are unbiased.
  • To adjust for the differences in the respondents.
  • To incorporate known information about the population expressed as control totals so that estimates will be more accurate.
