After Data Collection: Coding-An Educational Research Tool.
Shapiro, Peter D.
A brief and simple guide discusses the place and purpose of coding experimental data in the research process. The trade-offs involved unitizing data are reviewed; it is noted that a decision that increases reliability may reduce the validity of results, but without reliability there will be no validity at all. A discussion of categorizing data includes information on building the category set, the relationship of categories within a set, and designing the discrete-category code. Ways of calculating reliability are presented to allow the researcher to measure the equivalence of results when different coders classify the same data using the same set of categories. (JY)
