ABSTRACT
We are going to make some simplifying assumptions (approximations) to avoid setting ourselves up for failure by including too many variables and going for 100% accuracy. The problem of power becomes unmanageable if we try to understand all the dynamics—data grows over time, situations change depending on time of day or time of month. Rather we will sign up for simplifying assumptions, set up a solvable problem, and generate a useful, informative analysis.
