Document Summary

Coding: systematically reorganizing raw numerical data into a format that is easy to analyze using computers. Codebook: a document describing the coding procedure and the location of data for variables in a format that computers can use. Pre-coding: placing the code categories on the questionnaire. In a grid, each row represents a respondent, subject, or case. A column or a set of columns represent specific variables. Makes it possible to go from a column and row location back to the original source of data. Code checking: involves checking the categories of all variables for impossible codes. Contingency cleaning: involves cross-classifying two variables and looking for logically impossible combinations. Statistics: a set of collected numbers, and a branch of applied mathematics used to manipulate and summarize the features and numbers. Can be categorized by the number of variables involved: univariate, bivariate, multivariate. Frequency distribution: the easiest way to describe the numerical data of one variable: histogram, bar chart, pie chart.
