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.
Now the picture is not symmetric around the mean anymore. For a right skewed distribution, the mean is typically greater than the median. Also notice that the tail of the distribution on the right hand (positive) side is longer than on the left hand side.
