• Statistics: Types of Sampling
• Random Sampling
• This sample allows everyone in the population to have an equal chance of being picked.
• Random Number Generator
• Random Number table
• Systematic sampling
• Using a sampling frame, a starting point is chosen at random and thereafter regular intervals
• For  example, choosing every 15th house of 120, to obtain 8 houses.
• Cluster sampling
• Units are chosen in clusters that the population is chosen in, these are chosen at random
• For example, choosing households  of various streets
• The cluster should be dissimilar so that the sample must be representative of the population
• Quota sampling
• Sampling a selection of the population. Quotas specify a certain subgroup of the population
• For example, 50 females, aged 45-50
