Weekly update on merit distributions since the 5th of March.
As always, my statistics on percentage changes of merit distribution are different from @coinlocket$'s ones.
The difference mainly due to my comparison made to compare a specific figure of total merits distribute at specific week to previous median (not as of previous merits distributed as @coinlocket$ approach).
The current median has not changed too much since latest one, insignificant fall from 4405 to 4390, despite of the dramatic drop of total merit distributed last week.
Last week (start from 29/10/2018 to 04/11/2018), the total weekly distributed merits fell nearly 24.6% than median of previous period (from 05/03/2018 to 28/10/2018).
3302 and 4405 are the last week totally distributed merits and median of previous period, respectively, which have been used for the comparison in my analysis.
One more thing, 3302 is a low total weekly distributed merits, but the figure has still not been a potential outliers, which should be somewhere around 2.5k.
The figure has been outside the interquartile range, which ranges from 3903 to 4820.
The lower potential outliers calculate via the following formula:
Potential lower outliers = Q1 - 1.5*IQR = 3903 - 1.5*(4820- 3903) = 2528.
It means that we might have something very interesting to make a deeply analysis if the total merit distributed per week drops to around 2.5k at any specific week.
Additionally, by now, we have seen only one week that has a spike over the higher potential outlier. The mentioned week, when new required merit aims at Junior member rank and demotion implementation, has 9684 merits distributed in total.
The formula to calculate higher potential outliers is: Q3 + 1.5*IQR = 4820 +1.5*917 = 6196.
In a nutshell, weeks that have total distributed merits above 6.2k or below 2.5k should be taken into consideration because they are highly potential outliers. It is probably that the sorts of outlier-weeks occur due to significant changes in the forum rules/ systems, etc.
Of course, the exact value of outlier thresholds, both above and below, will change over time, but it will be somewhere around those points (2.5k and 6.2k).
* Note:- IQR = Q3 - Q1
- Q1: the 25th quartile
- Q3: the 75th quartile.
