1. Random Sampling

-Selection of members of a group haphazardly where every item has an equal chance of being selected e.g. to select 5 students to go for a tour from a class:

- Class members write their names on pieces of paper
- They are folded and put in a basket
- The basket is shaken and fives papers are taken out

2. Systematic Sampling
-Selection of members of a sample from an evenly distributed phenomena at regular intervals e.g. after every 10 items/members.

3. Stratified sampling
-Selection of members of a sample by breaking the population into homogenous groups e.g. to select 6 students to go for a tour:
-Break the class into boys and girls
- Select 3 student from each group by random or systematic sampling
- Combine units from each group to form the required sample.

4. Cluster Sampling
-Selection of sample by dividing the sample into clusters with similar characteristics then a sample is taken from each cluster and representative choices from each cluster are combined to form a sample e.g. to sample the housing cost an estate is chosen to represent each group and representative choices are chosen from each estate and combined to form a sample.
