From each description, identify or infer the target population, the sampling frame, the unit of analysis, and the type of sample. Discuss whether the sampling strategy will allow the researcher to form inferences about the target population based on the sample.

Problem: To study factors related to a diagnosis of depression in elderly individuals. Sample: A random selection of 150 of the 300 residents diagnosed with depression in one year while in a particular geriatric facility, and 340 randomly selected from the 850 residents in the same facility who were not diagnosed with depression during that year.

b. Problem: To obtain information on routes and types of transportation used by people traveling with the city. Sample: Council of Governments has computerized dataset of 110,000 trips made in one year; 10 percent of the trips are randomly selected for intensive analysis.

From each description, identify or infer the target population, the sampling frame, the unit of analysis, and the type of sample. Discuss whether the sampling strategy will allow the researcher to form inferences about the target population based on the sample.

a. Problem:

To study factors related to a diagnosis of depression in elderly individuals. Sample: A random selection of 150 of the 300 residents diagnosed with depression in one year while in a particular geriatric facility, and 340 randomly selected from the 850 residents in the same facility who were not diagnosed with depression during that year.

The target population is elderly individuals.

b. Problem:

To obtain information on routes and types of transportation used by people traveling with the city. Sample: Council of Governments has computerized dataset of 110,000 trips made in one year; 10 percent of the trips are randomly selected for intensive analysis.

The sampling frame is a specific geriatric facility.

Sampling Methodology It is incumbent on the researcher to clearly define the target population. Sometimes, the entire population is small enough to be included in the study. In other instances, the population is too large for the researcher to attempt to survey all of its members. Therefore, a small, but carefully chosen sample is used to represent the population. The sample is the actual group targeted either directly or indirectly and reflects the characteristics of the population from which it...

The list of individuals from which a sample is actually selected is called the sampling frame. Ideally, the sampling frame should list every individual in the population, but in practice this is often difficult. A sampling frame that leaves out part of the population is a common source of undercoverage. In the following questions select all choices that apply; to receive credit for the question you must select all the correct choices and only the correct choices. Question 1. A...
