How do you guys choose sample size for your self experimentation? (With A/B experimental design)
Do you calculate it?
Can I just use 80*365=29.200 as population size, if I assume that I will live for 80 years? (29.200 days)
When I do the calculation shown on the image, can I then assume that my results are correct in 95% of all cases with an margin of error of 5%?
Examples of my next 3 experiments:
- How does training my neck affect my neck pain? (A/B design)
- How does NOT eating gluten affect my focus? (A/B design)
- How does working less affect my focus? (A/B design)
