Statistical Consulting – Research Methodology

We can provide ample instruction on the methods used. For example, we determine the ideal sample size using a power analysis. The sample size is calculated from statistical power, effect size, and significance level. In addition, we operationalize your hypotheses and research questions. Additionally, our statistical consultants can select variables based on the hypothesis that they test. Finally, we assist you in the design phase of your research.
