Quiz zum Vortrag

1. Any random sample will be representative of the population about which it is used to make inferences
2. By randomly sampling, we ensure that separate outcomes do not affect each other
3. No one can guess the outcomes before they happen
4. Several software packages exist that will do the sampling for you
1. A census is not representative of the population
2. A census can be extremely expensive to carry out
3. A census may not give information about the population that is as accurate as what is obtained from a random sample
4. A census can be very complex
1. This list is known as the sampling frame
2. This list is known as the population
3. This list is known as the sample
4. This list is known as a census
1. We have used a convenience sampling scheme
2. We have used a voluntary response sampling scheme
3. We have used a cluster sampling scheme
4. We have used a stratified sampling scheme
1. This survey will likely suffer from response bias
2. This survey should not suffer from any bias because the respondents were selected randomly
3. This survey will likely suffer from nonresponse bias
4. This survey will likely suffer from undercoverage
1. To learn about the population
2. To learn about the sample
4. To learn about unknown things
1. 500
2. 100
3. 200
4. 300
5. 400
1. Benefits = 200 ; Costs = 100
2. Benefits = 100 ; Costs = 100
3. Benefits = 200 ; Costs = 200
4. Benefits = 150 ; Costs = 130
5. Benefits = 10 ; Costs = 0
1. Cluster sampling and Stratified sampling techniques are the same
2. Random sampling implies that the sample is representative of the population
3. Higher sample size is more accurate than small sample size
4. Sample is always smaller than population
5. The sampling strategy with the highest net benefit is chosen
