Option 1:

You can check out these learning materials in case your question can be self-answered.

• StatQuest: YouTube channel with short videos by Josh Starmer to explain important concepts in Statistics and Data Science. Popular videos:
  • PCA
  • Hypothesis testing
  • Statistical power
  • Sample size
  • P-hacking and power calculations
  • Neural networks
  • Linear models for t-tests and ANOVA
• What they forgot to teach you about R by Jenny Bryan
• Data Organization by Karl Broman
• Learning Statistics with R
• Statistical Rethinking course materials by Richard McElreath, accompanied by YouTube lectures
• Guide to Mixed Effects models (upcoming)

Option 2:

You have questions about sample sizes.

• Know that you need preliminary data to answer this question. You need to have an idea of effect sizes and variability, as well as the power that you aim to achieve.
• The sample size depends on what you want to achieve and with which methods (pairwise tests, ANOVA, linear models,…), yet it can sometimes be conveniently computed for simple pairwise tests as an rough estimate.
• Use this user friendly shiny app that automatically calculates sample sizes for pairwise tests: https://solislemus-lab.shinyapps.io/sample-size-shinyapp/.

Option 3:
