Random Sampling - GCSE Maths Definition

Random sampling refers to selecting a certain number of members from a population, as its name suggests, at random. In GCSE Mathematics, random sampling refers to the situation when every member of the population has an equal chance of being selected. Random sampling, as long as the sample size is large enough, has the benefit of reducing bias as it does not require any particular feature from a member, in order for it to be selected. Random sampling is usually carried out by allocating a unique number to each member of the population, and then using a random number generator to select numbers of the members to select.
