| randomised controlled trial | A clinical trial that involves at least one test treatment and one control treatment, concurrent enrollment and follow-up of the test- and control-treated groups, and in which the treatments to be administered are selected by a random process, such as the use of a random-numbers table. Treatment allocations using coin flips, odd-even numbers, patient social security numbers, days of the week, medical record numbers, or other such pseudo- or quasi-random processes, are not truly randomised and a trial employing any of these techniques for patient assignment is designated simply a controlled clinical trial.

There are many minor characters in the various versions of The Hitchhiker's Guide to the Galaxy, by Douglas Adams. In fact, defining a major character is rather difficult. If the major characters are those the plot focuses on, they are Arthur Dent, Ford Prefect, Zaphod Beeblebrox, Marvin and Trillian, with the possible inclusion of Slartibartfast, Random Dent and Fenchurch. If they are defined as characters appearing in all the books, they are only Ford Prefect and Arthur Dent. ...

| random genetic drift |
Genetic drift is a mechanism of evolution that acts in concert with natural selection to change the characteristics of species over time. It is a stochastic effect that arises from the role of random sampling in the production of offspring. Like selection, it acts on populations, altering the frequency of alleles and the predominance of traits amongst members of a population, and changing the diversity of the group. ...
