SOCI 217 Chapter Notes -Codebook, Univariate, Continuous Or Discrete Variable
Document Summary
The process of converting data to a numerical format. Quantifying data: from coding data is transformed into numeric form. Developing code categories: 1) begin with a well-developed coding scheme to capture all the available criteria can be done so by adding more categories/criteria (ex. 411), code should also be mutually exclusive and exhaustive. Codebook construction: a codebook is a document that describes the locations of variables and lists the assignment of codes to the attributes composing those variables. Data entry: inserting the data into somewhere readable or using optical scan sheets that converts data into numeric value. Data cleaning: process of detecting and correcting coding errors. There are 2 types: 1) possible-code cleaning, 2) contingency cleaning. Possible-code cleaning: making sure that only pertinent code appears. Contingency cleaning: data entered concerning variables of interest do have data. There"s no meaningful knowledge from the gap between married and single: detail versus manageability.
