You’ll continue reading about research methods that use quantitative evidence, and building your matrix (or table). This week, you’ll use a Rapid Critical Appraisal form to help you answer important questions about the quality of a primary quantitative research article. These questions will help you learn to evaluate study strengths and weaknesses. Usually, quantitative methods will use structured instruments to collect data which will then be analyzed statistically. The articles you are using to practice the appraisal process should become a part of your evidence you are compiling to answer your practice question.
The statistics module will guide you through understanding power analysis and effect size. Power analysis is a method for estimating in advance how big the sample size should be in order to detect a true difference between groups in the study. The effect size is related to the strength of the relationship between the independent variable and the dependent variable.
