Background: Regression to the mean (RTM) is a statistical phenomenon that can make natural variation in repeated data look like real change. It happens when unusually large or small measurements tend to be followed by measurements that are closer to the mean. 2014-09-18 2021-04-13 2015-12-29 Regression to the mean - examples Suppose you run some tests and get some results (some extremely good, some extremely bad, and some in the middle).

According to Galton, “reversion is the tendency of the ideal mean filial type to depart from the parental type, reverting to what may be roughly and perhaps fairly described as the average ancestral type.” If this process of reversion were not at work, i.e., if large peas produced ever-larger peas and small Regression to the mean occurs here because you’re comparing the number of heads the selected person gets not simply with what they got before, but with the most heads that any of the 10 observed. You’ve deliberately picked an extreme number of heads and it’s almost inevitable that when trying again, they’ll get fewer heads the second time.

High performers show disappointing results when they fail to continue delivering; strugglers show sudden improvement.

It happens when unusually large or small measurements tend to be followed by measurements that are closer to the mean. Regression toward the mean refers to the principle that, over repeated sampling periods, outliers tend to revert to the mean. High performers show disappointing results when they fail to continue delivering; strugglers show sudden improvement. Regression toward the mean (RTM for clarity in this article) is the concept that any given sample of data from a larger population (think April stats) may not be perfectly in line with the underlying average (think true talent/career stats), but that going forward you would expect the next sample to be closer to the underlying average than the Regression to the Mean There’s a phenomenon called “regression to the mean” in statistics. My layman’s explanation is that something that’s far out of the norm tends to return toward the norm when you continue to measure it.

It is far more robust in the data than, say, the much-discussed middle-income trap. Furthermore, statistical analysis of growth reveals that in developing countries, episodes of rapid growth are frequently punctuated by discontinuous drop-offs in growth. Regression to the mean is really a phenomenon driven by the relative strength of the longer term underlying factors and shorter term proximal factors. If the underlying factors dominate the more proximal ones, then the we would expect to see less regression to the mean. Therefore regression toward the mean becomes an important practical phenomenon.
