What’s the full sleep data, or at least the variance? 31 may be large enough. And if it’s not, getting more by the end of the year may not make a big difference

What’s the full sleep data, or at least the variance? 31 may be large enough. And if it’s not, getting more by the end of the year may not make a big difference. Power only increases at the square root of the sample size.
- mg 3y agoEnd of next year. So in theory I could 10x the number of data points. But its one of the more annoying experiments to let a coin decide if you have to take another walk :) So I'm not sure how often I will do that. I'm pretty convinced already that walking more is a good thing. I'm in a hurry right now, but I will probably write a full blog post about the steps-sleep relationship with p values and everything some time next year.
