biased/loaded experiment Explanation: If you're using a completely regular die, there will be a one in six chance of its falling on any one face. As soon as it becomes irregular, for example by being heavier on one side, the experiment becomes biased. A drawing pin/thumbtack is an extremely irregular "die", and heavily loaded or biased. The only way you can calculate the probability of its falling with the point up is to throw it lots of times. If I'm given the outcome of a number of dice rolls (say, 5 twos, 8 threes, etc), is there a way to assign a probability that the dice are biased or unbiased? http://math.stackexchange.com/questions/267946/how-can-i-tel... Probability with loaded and fair dice http://math.stackexchange.com/questions/2137754/probability-... (When you found "fair" you were in the right track, but I'm not sure an experiment can be fair or unfair.) |

non-randomized experiment Explanation: In the statistical theory of design of experiments, randomization involves randomly allocating the experimental units across the treatment groups. For example, if an experiment compares a new drug against a standard drug, then the patients should be allocated to either the new drug or to the standard drug control using randomization. https://en.wikipedia.org/wiki/Randomized_experiment |
