Document Summary

Surveys are correlational research: causality may not be inferred. Some survey research makes predictions: predictor variables and criterion variables. Defining constructs: research has shown that this is the most important stage in survey design. Types of questions: demographic information, open-ended items, no specific set of alternative answers, critical incident technique, analyzed with content analysis, close-ended (restricted) items, specific set of alternative answers, partially open-ended items (other category, forced choice items, rating scales. Scales: categorical scales (nominal, participant assigns self to a category, categories must be mutually exclusive, continuous scales (interval/ratio, ranked scales (ordinal) Summative scales: each item contributes equally to the score, cumulative scales, each item represents an increasing amount of the attribute being measured. Scaling models: likert scales, the semantic differential, visual analogue scales, guttman scales. Semantic differential: another summative scaling method, measures individual"s feelings about a particular construct by scaling between two extremes, only the extreme anchors are labelled.
