Data collection methods & Annotatted

Specific methods of data collection (e.g., surveys, interviews, observations) produce specific types of data that will answer particular research questions, but not others; so here too, as covered in previous weeks, the research questions inform how the data will be obtained.  Furthermore, the method used to collect the data may impact the reliability and the validity of that data.

For this Discussion, you will first consider sampling strategies. Then, you will turn your attention to data collection methods, including their strengths, limitations, and ethical implications. Last, you will consider measurement reliability and validity in the context of your discipline.

Position A: Probability sampling represents the best strategy for selecting research participants.

Post a restatement of your assigned position on sampling strategies. Defend your position with examples and support from the scholarly literature. Next, select a data collection method and briefly explain its strengths and limitations. Then, identify a potential ethical issue with this method and describe a strategy to address it. Last, explain the relationship between measurement reliability and measurement validity using an example from your discipline.

Be sure to support your Main Issue Post with reference to the week’s Learning Resources and three (3) other scholarly evidence in APA Style.

ANNOTATED

•      Locate six articles on a research topic of your interest—two quantitative research articles, two qualitative research articles, and two mixed methods research articles—published in peer-reviewed journals.

•      Prepare an annotated bibliography that includes the following:

◦       A one-paragraph introduction that provides context for why you selected the research articles you did.

◦       A reference list entry in APA Style for each of the six articles that follows proper formatting. Follow each reference list entry with a three-paragraph annotation that includes:

▪       A summary

▪       An analysis

▪       An application as illustrated in this example (see example below)

◦       A one-paragraph conclusion that presents a synthesis of the six articles.

Format your annotated bibliography in Times New Roman, 12-point font, double-spaced. A separate References list page is not needed for this assignment.
