Answer 1

Random sampling is one way of ensuring that a sample is representative of the population.

Ramdom sampling is a technique in which each member of the sample has an equal chance of being selected. One of the most common methods of performing this is through the use of a lottery, where each individual is assigned a number, which is placed in a bowl along with teh others. All the numbers that are randomly selected are chosen as subjects. A variant of this is through computerised random sampling. It is one of the most effective ways of ensuring that the population is represented without any bias. In case it is not, it is not as sampling error.
