"## Collecting and Interpreting Data\n",
"### Sampling\n",
"- Simple random sampling\n",
" - Random procedure\n",
" - e.g. drawing tickets, random number generator\n",
" - In a finite sample space, all candidates have an equal chance of being selected\n",
" - Sampling is done without replacement\n",
" - Selections are independent\n",
"- Cluster sampling\n",
" - Only some subgroups of a sample space are selected\n",
" - Only appropriate when subgroups are reasonably representative of the entire sample space\n",
"- Opportunity sampling\n",
" - Selection by opportunity\n",
" - e.g. interviewing passers by on a street\n",
"- Stratified sampling\n",
" - Used when sample space can be divided into subgroups (strata)\n",
" - ... to ensure all strata are sampled\n",
" - Weighting needs to be used if numbers of samples from each strata are not proportional to the size of the strata\n",
"- Quota sampling\n",
" - Same as stratified sampling with a quota for each strata\n",
"- Self-selected sample\n",
" - Individuals chose to be sampled\n",
" - e.g. online poll\n",
"- Systematic sampling\n",
" - Systematic procedure\n",
" - e.g. every 10th person on alphabetically sorted list"
