Efficacy
Statistical methods / analysis
Descriptive statistics will be used to explore the data. Although this is a small pilot study inferential analysis is appropriate given the power and effect size calculations. A power calculation suggests that this study has 80.0% power to detect an effect size of 0.221. An independent groups t-test will be used to detect the treatment difference between groups. Results from hypothesis testing will be treated as preliminary and interpreted with caution.
