Microeconomics for the laypeople!
Amazingly, statistics is taught in concordance with calculus and as a prerequisite of microeconomics for good reason, to which is then used in econometrics, but that uses macroeconomics, and accounting which should be taught in that order, versus the Johns Hopkins University curriculum, now.
N sample size is much like that of the yearly changes of rates per period, and I often argue, especially with the seasons affecting disease as well as expenses, err, sorry, product, requires 100 years to assign any meaningful significance. We do, however, wish to understand the value of utility.
Low supply is 10 marginal units, entrants of people, utility that is price as a square by sortition. If you actually sorted people by survey without a market maker or the bid and ask taking the other up for the outright sale of inventory (market making, volume on bid is aggregate selling per time period).
Labor is overhead.
