Designing a study or experiment with the statistical analysis in mind is the best thing you can do to insure that you will get meaningful results. Some of the considerations when designing your study include:
- your objectives: describing a population, making predictions/forecasting, testing specific hypotheses
- design: paired vs independent samples, controls, blocked, nested, randomized, balanced, full factorial, Latin square, avoiding confounding variables and biases, etc.
- statistics: candidate statistical approaches, pseudoreplication, sample size and statistical power
I will insure that your study or experiment is the most efficient and appropriate to reach your objectives given the time, resources, and other constraints specific to your project.
