Determine what type of sampling is used (Simple Random Sampling, Stratified Random Sampling, Systematic Sampling, Cluster Sampling, or Convenience Sampling).  1. To get a sense of election outcomes, a political group chooses ten precincts to conduct a survey of voters in those areas.

determine what type of sampling technique is used (Simple Random Sampling, Stratified Random Sampling, Systematic Sampling, Cluster Sampling, or Convenience Sampling). 5. A researcher wants to select ten students for a survey. Each student’s name is placed in a hat and 10 names are selected.

Identify the sampling techniques used, and discuss potential sources of bias (if any). Explain. After a tsunami, a disaster area is divided into 250 equal grids. Thirty of the grids are selected, and every occupied household in the grid is interviewed to help focus relief efforts on what residents require the most. What type of sampling is used? A. Stratified sampling is used, since the disaster area is divded into grids, and a random sample is taken from each grid. B. Cluster sampling is used, since the disaster area is divded into grids, and a random sample is taken from each grid. C. Stratified sampling is used, since the disaster area is divided into grids, and some of those grids are selected and everyone in those grids is interviewed. D. Cluster sampling is used, since the disaster area is divided into grids, and some of those grids are selected and everyone in those grids is interviewed. What potential sources of bias are present, if any? Select all that apply. A. Certain grids…

Telephone surveys may use a telephone directory to identify individuals for study. Speculate on the type of household that would be uncovered by using this sampling frame

In a study, the sample is chosen by writing everyone's name on a playing card, shuffling the deck, then choosing the top 20 cards. What is the sampling method? Ostratified Ocluster O random convenience

A researcher is interested in determining the spending habits of the employees in a particularly large law firm . The researcher wants to gather information from at least 50 of the 167 employees . Assume the researcher has complete control over how to pick the residents to collect this data. In the box below, pick a sampling method: Random, Stratified, SystematicCluster, or Voluntary, and describe how to use it in this scenario to collect a sample that will represent the whole law firm Your description should show understanding of the method you chose and be in the context of this scenario - not just a definition of the type of sampling.

What is the sampling method described?   The population is divided into groups where similar cases are grouped together. Then second sampling method is employed to sample the cases within each group.   a. A simple random sampling   b. Stratified sampling   c. Cluster sampling   d. Multi-stage sampling

A marketing expert for a particular chain of restaurants is planning a survey in which 510 people will be randomly selected from each age​ group: 10-19,​ 20-29, and so on.       What type of sampling is​ used?     Convenience sampling   Simple random sampling   Systematic sampling   Stratified sampling   Cluster sampling Is the procedure likely to yield a representative sample or a biased​ sample? Explain why.     A. The procedure is likely to yield a representative sample because it covers every age group.   B. The procedure is likely to be biased because people from those age groups are not evenly distributed throughout the population.   C. The procedure is likely to yield a biased sample because younger people​ don't know what they want and should be studied separately.   D. The procedure is likely to be representative because 510 people from each age group form a large sample size.
