1
A sample where every member of the population has an equal chance of being selected
2
More likely to be representative of a population , Removes bias
3
Simple Random Sampling, Systematic Sampling, Stratified Sampling
4
Each unit in the sampling frame is allocated a unique number, A selection of numbers is chosen at random using a device to choose the numbers at random (e.g. calculator), or using "lottery" sampling
5
Place each unit of the sampling frame in a randomly ordered list, Choose units at regular intervals in this list from a random starting point
6
Divide the sampling frame into mutually exclusive categories of equal proportion to the entire population, Take a random sample from each category
7
Free of bias, Easy and cheap to implement for smaller populations and samples, Each unit has a known and equal chance of being chosen
8
Unsuitable for larger populations , Requires a sampling frame
9
Simple and Quick to use, Suitable for larger populations and samples
10
Requires a sampling frame, Can introduce bias is the sampling frame isn't random
11
Sample reflects population structure, Guarantees proportional representation of groups within a population
12
Must be distinct groups, Unsuitable for larger populations, Needs a sampling frame
