Document Summary
Key terms: concepts: ideas or mental representations of things. Concepts may be independent or dependent variables. For example, the concept social mobility can be used as a possible explanation of certain attitudes or as something to be explained: coding: transforming a measure into numbers. Can be done in both qualitative and quantitative data. : in measuring life satisfaction, respondents who say they are very satisfied may be given a code of 1 , which is then recorded in a file. Every data set has a coding manual. Measurement allows a delineation of small or fine differences between people or issues we are interested in. Measurements provide a way to identify and gauge those differences with consistency. It allows us to estimate what the relationship is between concepts and the strength of that relationship. Indicators tell us (indicate) that there may be a link and tell us how strong the link may be: usually, one indicator for each concept is adequate.
