Document Summary

Scaling: when standard scales do not exist: likert. One of the founders of questionnaires and doing things through samples: semantic differential. For each statement, indicate the strength of your agreement or disagreement: cognitive knowing, affective feeling, behavioural the tendency to act. Purposes for taking a sample: describing a population on the basis of incomplete data using a sample that you hope will reflect the properties of the population and represent it. It should be a miniature replica of a population ideally: can test hypotheses with regards to a population or comparing populations. London may be different from sarnia sampling each population and test hypotheses. Sample frame: best list we can draw of members of the population often falls short of the population, some members just can"t be identified or included on the list for many reasons. Types of sample: non probability sample: a sample which the likelihood of selecting any given member of population is unknown.
