Assignment: Case experimental Research

Week 7 assignment 2 Evidence Based Project Proposal For your Dropbox assignment this week, you will write Part 4, the Methods section of your project proposal that consists of plans for conducting the study of the intervention and methods of evaluation. Use the titles of each bullet point in your paper. In a two- to three-page APA formatted paper: Study design: Briefly describe the study design indicated by the question (experimental, quasi-experimental, descriptive). Setting/sample: Briefly describe the setting for the study, who your study participants will be, and how these participants will be chosen. Will random sampling or a sample of convenience be used? Confidentiality: How will you protect the confidentiality of your participants? Procedures/intervention: Discuss the intervention you will implement and the procedures you will use in enough detail that others could replicate the study. Instruments/scales and measurement of outcomes: Describe the instruments you will use to measure changes and whether they are quantitative, qualitative, or of a mixed design. If they have been tested previously, include reliability and validity data. Data collection: Explain plans for data collection including: Methods of collection, i.e., interviews, paper and pencil testing, etc. Testing frequency. Will you gather baseline data prior to the intervention? Will you employ repeated measures such as pre- and posttests?The prefix quasi means “resembling.” Thus quasi-experimental research is research that resembles experimental research but is not true experimental research. Although the independent variable is manipulated, participants are not randomly assigned to conditions or orders of conditions (Cook & Campbell, 1979). Because the independent variable is manipulated before the dependent variable is measured, quasi-experimental research eliminates the directionality problem. But because participants are not randomly assigned—making it likely that there are other differences between conditions—quasi-experimental research does not eliminate the problem of confounding variables. In terms of internal validity, therefore, quasi-experiments are generally somewhere between correlational studies and true experiments.
