Research Methods - Snowball Sampling

Snowball sampling is when you choose one participant and ask them to ask their friends to take part too. This can be used when you're researching a group that's quite hard to get
access to, for example, criminals.

Research Methods - Random Sampling

A random sample is one where everyone has an equal chance of being picked. For example, putting everyone's name into a hat would be a random sample as they all have an equal chance of being picked. This method is regarded as representative because it assumes that everyone has an equal chance to be picked,however, it can sometimes be considered as not being representative due to the possibility of picking people who have similar characteristics, when you are, in fact, looking for a random sample.
