That way: 1  you avoid that players get a too high SR when carried by their team. especially happens during the placement matches, were they might have had too much luck that got them placed in the right team most of the time. 2  players get a SR value that is a better representation of the players Skill.
Skewed Distribution Skewed distribution is a statistical term that measures âasymmetryâ (lack of similarity) in a âbell curveâ (the bell-shaped graph that occurs when plotting data based on normal meaured traits). In ânormal distributionâ there should be a roughly equal number of occurrences of a measured trait on both sides of the mid-point of the bell curve. The âskewnessâ (percent of difference) statistic measures how great a change there is in the number of trait occurrences on either side of the mid-point of the curve.
The dictionary meaning of clump is âsit togetherâ. And the meaning of âclumped distributionâ carries no special meaning. To the best of my understanding a clumped distribution is when things stay together. A uniform distribution is when a random variable is uniformly distributed in its entire range. A clumped distribution is when it occurs in clusters. A good example of clumped distribution will be the distribution of human population centers on the map of a country. Human population is clustered around big cities. In fact, most distributions should be clumped. If I were to plot the heights of adult humans, it may be clumped around two main centers (average heights of men and women). Even wild flowers in a meadow are clumped around where ever they happen to be. An image search for âclumped distributionâ shows you tens of examples.
