Describe computation of statistics for the sample profile.

Describes, in detail, statistical and non-statistical analysis to be used and procedures used to conduct the data analysis. Quantitative Studies: (1) describe data file preparation (descriptive statistics used to check completeness and accuracy; for files from different sources, possibly aggregating data to obtain a common unit of analysis in all files, necessarily merging files (using the key variable defining the unit of analysis); (2) computation of statistics for the sample profile; (3) computation of (subscales and) scales; (4) reliability analysis for all scales and subscales; (5) computation of descriptive statistics for all variables of interest in the study (except those already presented in the sample profile); (6) state and justify all statistical procedures (“tests”) needed to generate the information to answer all research questions; and (7) state assumptions checks for all those statistical procedures (including the tests and / or charts to be computed).
