Random Sampling
A sampling method where every member of the population has an equal probability of selection, and selections are independent. Often implemented using random number generators or sampling tables.
Real World
A pharmaceutical company testing a new drug assigns participants using a computer-generated random number list so that each patient on the trial register has the same chance of receiving the treatment.
Exam Focus
When asked to 'describe' random sampling, name the tool used (random number table/generator) and state equal probability explicitly.
