Homework: Sampling, Scales of Measurement and Article Review
This homework will require the student to explore and understand various types of sampling procedures and scales of measurement. In addition, the student will discuss the various components of an article and determine specific statistical analysis and other pertinent details. These will be discussed in the context of the overall findings.
Section 1
Answer the following statements:
I. In your own words, define a Population.
II. In your own words, define a Sample.
III. Provide an example of a research scenario (use your dissertation scenario!!) and then discuss the Population and the Sample in the context of the scenario (2-3 sentences).
IV. Define Bias in the context of research (2-3 sentences).
V. Identify, define, and provide an example of the four levels of measurement.
Retrieve and read the guide entitled Overview Sampling Procedures published by the division of System Managements for Human Services from Fairfax Co., VA.

Section 3: Next, choose 1 (one) recent quantitative article (published in 2015 or later) from a peer-reviewed journal and answer the following questions:
I. Sampling Procedures
1. Describe the characteristics of the population studied.
2. Identify sampling procedures (e.g., simple random sampling), and explain why it was selected.
3. Indicate the size of the sample.
4. What was the response/participation rate? How did those who responded or participated differ from those who did not? How was this addressed?
II. Data Analysis
1. What statistical analysis was conducted?
2. What were the units of analysis (e.g., individual, group, or program)?
3. What was the DV and what was the level of measurement for the DV?
4. Was the information presented in the figures and tables clear and was it discussed in the text?
III. Findings
1. What were the study findings? Were they discussed and described clearly and accurately? Were explanations proposed for any anticipated and unanticipated findings? Were the results substantively important? Were conclusions well grounded in the findings?
2. Was the study conducted in an objective fashion? Is there any evidence of bias?
