Sampling: Random

Advantages

In large numbers provides the best chance of unbiased representative sample of a target population
Avoids bias as you are randomly picking participants from for example a hat.

Disadvantages

The larger the population, the more difficult it is to sample randomly as compiling a list of everyone becomes more impractical.
True random sampling is very rare.

Evaluation

True random sampling only occurs when every member of a target population has an equal chance of being selected.
