  1. 1The response rate is the percentage of people out of the total number available who respond to a survey
    1. AVerdadero
    2. BFalso
  2. 2A [blank_start]simple random sample[blank_end] is when each member of the population has an equal probability of being selected using random sampling. The [blank_start]advantage[blank_end] of this is that is [blank_start]reduces[blank_end] sampling error by choosing from all members of the population to best represent the population. The [blank_start]disadvantage[blank_end] of this is that it is [blank_start]difficult[blank_end] to ensure that each member of a large population can be chosen in a sample.
    1. Aadvantage
    2. Bdisadvantage
    3. Creduces
    4. Dincreases
    5. Edisadvantage
    6. Fadvantage
    7. Gdifficult
    8. Heasier
    9. Isimple random sample
    10. Jstratified random sample
    11. Kcluster random sample
  3. 3A [blank_start]cluster random sample[blank_end] is when a cluster of individuals are identified and then a subset of clusters is randomly chosen to sample from. The [blank_start]disadvantage[blank_end] with this is that it can [blank_start]ignore[blank_end] segments of the population that aren't in the clusters chosen for the sample. The [blank_start]advantage[blank_end] with this is that it makes it [blank_start]easier[blank_end] to choose members randomly from smaller clusters to better represent the population.
    1. Acluster random sample
    2. Bsimple random sample
    3. Cstratified random sample
    4. Ddisadvantage
    5. Eadvantage
    6. Fignore
    7. Ginclude
    8. Hadvantage
    9. Idisadvantage
    10. Jeasier
    11. Kharder
  4. 4A [blank_start]stratified random sample[blank_end] is when members of a population are selected such that the proportion of a group in the sample is equal to the proportion of that group in the population using random sampling. The [blank_start]advantage[blank_end] with this is that it [blank_start]reduces[blank_end] bias due to an identified characteristic of the population by equating proportions in the sample and the population for that characteristic to better represent the population. The [blank_start]disadvantage[blank_end] with this is that it can be [blank_start]difficult[blank_end] to ensure equal probability of being chosen from a large population.
    1. Astratified random sample
    2. Bsimple random sample
    3. Ccluster random sample
    4. Dadvantage
    5. Edisadvantage
    6. Freduces
    7. Gincreases
    8. Hdisadvantage
    9. Iadvantage
    10. Jdifficult
    11. Keasy
  5. 5A [blank_start]haphazard/volunteer[blank_end] sample is when members of the population are chosen based on convenience and on who volunteers. The [blank_start]advantage[blank_end] of this is that it is [blank_start]easier[blank_end] to obtain than probability samples. The [blank_start]disadvantage[blank_end] of this is that it may not represent the population properly due to selection bias because random sampling is not used.
    1. Ahaphazard/volunteer
    2. Bquota
    3. Cadvantage
    4. Ddisadvantage
    5. Eeasier
    6. Fharder
    7. Gdisadvantage
    8. Hadvantage
  6. 6A [blank_start]quota[blank_end] sample is when members of the population are selected such that the proportion of a group in the sample is equal to proportions of that group in the population. The [blank_start]advantage[blank_end] of this is that it is [blank_start]easier[blank_end] to obtain than probability samples and allows for [blank_start]better[blank_end] representation of a characteristic of the population. The [blank_start]disadvantage[blank_end] of this is that it may not represent the population due to selection bias because random sampling is not used.
    1. Aquota
    2. Bhaphazard/volunteer
    3. Cadvantage
    4. Ddisadvantage
    5. Eeasier
    6. Fharder
    7. Gbetter
    8. Hworse
    9. Idisadvantage
    10. Jadvantage
  7. 7What is the difference between probability samples and convenience/purposive samples?
    1. AProbability samples are chosen such that the individuals are chosen with a specific probability and convenience/purposive samples are chosen so the probability can't be determined
    2. BConvenience/purposive samples are chosen such that the individuals are chosen with a specific probability and probability samples are chosen so the probability can't be determined
    3. CProbability samples are better than convenience/purposive samples
    4. DConvenience/purposive samples are better than probability samples
  8. 8Students being randomly chosen from a register is an example of what type of sample?
    1. ASimple random sample
    2. BCluster random sample
    3. CStratified random sample
  9. 9Registered voters from the Labour party and the Conservative party are randomly selected to the proportion of registered voters from each party in the UK. What type of sampling is this?
    1. AStratified random sample
    2. BCluster random sample
    3. CSimple random sample
  10. 10I have decided to sample shop keepers for my research. To do this, I first identified all corner shops in Bristol and then I randomly chose 10 corner shops of which to take my sample from. What sampling technique did I use?
    1. ASimple random sample
    2. BCluster random sample
    3. CStratified random sample
