It means it wasn’t controlled, that mere chance cause it (whatever it is). Random is not the same as merely being mixed, or disorganized, or no discernable pattern. If I take different densities of different sizes of pebbles and I put those pebbles in a bottle and I gently shake the bottle, the pebbles, due to their size and shape and density and how I shake the bottle will settle. Though I might be able to discern any pattern, though a different mix of pebbles or a different type of shaking could result in a near infinite settlings, the settling wasn’t random. If I use all the same size and shape and density of pebbles, and I shake the bottle enough that every pebble has an equal chance of being in every position—now I achieve, or for all practical purposes, achieve a random arraignment of pebbles. Randomness is not achieved unless every possible outcome (every pebble location, every coin or die toss outcome, every card that can be dealt) that can occur has an equal change of occurring. If any outcome has a greater chance of occurring than another outcome (e.g., heads more than tails on a coin toss) we know instinctively that something is not right. The reason a coin toss is considered fair is because it is random, i.e., there is no impartiality or bias in the event, heads and tails had an equal and random probability of occurring. There is an argument that noting is truly random, that if we enough information we could predict everything perfectly. Philosophically this may be true but we live in a real world where multiple forces and sequences of events affect things to the point where we can’t predict coin tosses (using fair coins and tossing the coins in a random fashion). Numerous, mostly undetectable and/or uncontrollable forces and imperfections influence every process and outcome. We cannot make a perfect circle nor a perfect drill bit. We cannot perfectly repeat every shot of the basketball. We cannot make two perfectly identical nails or ballot moves. Do not think that every mistake or error is random; most are not; they have a cause, a special , assignable , or attributable cause (even though we may be unaware of the cause). We cannot do anything about random error (which may be termed common cause or expected error). The oldest and core part of quality as a profession or discipline is to reduce non-random error. Therefore, it would be very useful to separate random errors (which you cannot control or eliminate) from non-random errors. Sometimes the cause of the error leads to an obvious and clear mistake. Often, mistakes are not clear.
