In the case of schedules, the distribution almost always tend to be right skewed as there is a finite amount that it can shorten, but an infinite amount that it could extend (possibly never be finished). Because of this right skewedness, the Mode (most likely), P50, and the Mean begin to diverge. Lets take a look at the below graph.

P90 and P10 are low and high estimates respectively. P90 means 90% of the estimates exceed the P90 estimate. It does not mean that the estimate has a 90% chance of occurring – that is a very different concept. The central limit theorem indicates that the P50 estimate has more chance of occurring than the P90 and P10 estimates.

Vanligvis brukes enten P10 og P90 eller P01 og P99. I praksis har det vist seg at P10 og P90 er bedre egnet enn på grunn av at folk flest ikke er i stand til å forestille seg hvor bra eller dårlig ting virkelig kan gå i ekstreme tilfeller. Men dette er avhengig av både hvilket domene

The easy mistake would be to read the P90 level of confidence as being the value of £1,002.9k displayed next to the 90% figure in the graph. However, this is the 90th percentile in the cumulative probability curve, beyond which only 10 per cent of simulated values lie, and is thus the P10 confidence level; an optimistic forecast which companies upon which most organisations would not base

But before we can investigate into these terms, we must first understand the definition of risk. Cumulative Pxi: The probability is at most x% that the output variable i will be less than its Pxi value (P10 is a low estimate, P50 is median, and P90 is a high estimate of variable i). The terms "at least" and "at most" appear in the above definitions because Pxi and Pyi values can be the same.
