I will calculate your sample size and advise which statistical test to use

NOT SURE HOW MANY PARTICIPANTS YOU NEED, OR WHICH TEST TO RUN?

Two of the most common questions in research, answered properly and fast.

BASIC - SAMPLE SIZE CALCULATION

Tell me your study design, expected effect size and power, and I will calculate the sample size you need and write the justification paragraph for your proposal, ethics application or methods section, with the formula and reference cited.

STANDARD - WHICH TEST SHOULD I USE?

Send me your research question and your variables. I will tell you exactly which statistical test is appropriate, why, what assumptions it requires, and how to report the result. Comes as a short written guide, not a one-line answer.

PREMIUM - ANALYSIS PLAN

A complete written statistical analysis plan for your study: sample size, every test mapped to every hypothesis, planned tables and figures. This is what supervisors and ethics committees ask for, and it saves you from discovering your design cannot answer your question after data collection.
