  • 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
