Characteristics and preparation of the data to be analyzed 1. segmentation of the population or a sample group of at least 2 groups (must know beforehand whether to split a few analysis group) 2. Select an independent variable that is expected to cause a split in the Group 1 are different. 3. the variables (variables that are resolved or being predicted) is divided into 2 or more groups, ranging from the level of measurement in section name (Nominal Scale), or sort the ratings scale (Ordinal Scale) and if the data is in a different level of information is a complex group of variables. Prior to analysis. 4. the independent variable (the variable used in the classification, or variables that are used to predict) is variable. Continuous level measurement is in section antonphak, (IntervalScale) or ratio scale (Ratio Scale) and if the data is in another level, variable transforms to a dummy (Dummy Coding) prior to analysis.
