Quantitative Research to Determine Validity and Reliability Research Methodologies
Develop and describe an experiment or quasi-experiment – NOT a single-case evaluation design –for evaluating the identified problem area. The methodology for the study you design should contain a high degree of internal validity and scientific rigor. Most threats to internal validity should be controlled, and reasonable efforts should be made to minimize measurement bias. This proposal should provide a concise description on how the study is to be conducted in order for readers to be able to conduct the study themselves from your description. Write this section in future tense (i.e., “will do”).
- Research Design: Identify and describe the specific research design.
- Sample: Describe the sampling procedure, how the recruitment and selection process will occur, consent process, the study site (where you will find your subjects), and the projected number of subjects (n=).
- Procedures: Describe the process of implementing your study. What, exactly, would you do once you have the subjects? (Be extremely specific.)
- Measurement: Identify at least 2 dependent variables (or 2 ways to measure one dependent variable) and 5 independent variables. Name the concepts and the variables. Provide your operational definition, identify specifically how the variables will be measured (question, scale, standardized measure, etc.), and identify the level of measurement (dichotomous, categorical, interval).
