As an example of the cumulative distribution, we will build and analyze the cumulative frequency distribution for rolling two standard number cubes.
If we sum all possible combinations from two standard cubes, we will get the following values:
Each value has its frequency and probability, see table below:
The cumulative frequency graph can be built according to the values in the table:
Position of the median:
Position of the lower quartile:
Position of the upper quartile:
This tells us that the difference between maximal and minimal value in the middle 50% is equal 4.
