Document Summary

Surveys provide snapshot view of attitudes, behaviours and beliefs. Interviews: structured (follow a decision tree) or unstructured (focus group, need to be careful of bias) Can increase the number of people that respond to your questionnaire (response rate) by making it seem brief and interesting, stressing importance of participation, offering gifts or ensuring confidentiality. Representative sampling: when sample is the same as the population in all- important aspects. Probability sampling: when everyone in the population has a known chance of being chosen to be a part of the sample. Simple random sampling: when sampling frame is obtained, number from 1 to however many people there are and then use random number generator to see who is included in sample. Systematic random sampling: when sampling frame is already in random order, we choose a number and every nth person is included in the sample.
