Knowledge and Skill Requirements
The tutorial was structured so that you can start anywhere and move around as you wish. However, later modules build on earlier modules and they assume some familiarity with statistics, dietary data and analysis , and nutritional epidemiologic concepts.
Modules 15
These modules require:

basic familiarity with an Internet browser and computer; and

no knowledge of statistical software or programming or previous experience with NHANES dietary datasets and files.
Modules 611
These modules require:

basic knowledge of NHANES dietary datasets and files;

basic knowledge and skills in statistical analyses (e.g. ability to run frequently used descriptive and reference statistics, and correctly interpret the results); and

basic knowledge and skills in SAS and/or SUDAAN statistical software.
Modules 1216
These modules require:

basic skill in preparing an analytic dataset with NHANES dietary data;

basic knowledge of descriptive and inferential statistics, and epidemiologic concepts;

basic knowledge and skills in statistical analyses (e.g., ability to run frequently used descriptive and reference statistics, and correctly interpret the results); and

basic knowledge and skills in SAS and/or SUDAAN statistical software.
Modules 1722
These modules require:
basic skill in preparing an analytic dataset with NHANES dietary data;

proficiency in descriptive and inferential statistics, correlation and regression analyses methods, and epidemiologic concepts;

proficiency in descriptive, inferential, correlation, and regression analyses (e.g., ability to run advanced statistical analyses and correctly interpret the results);

proficiency regarding statistical considerations of dietary data analyses; and

proficiency in SAS and/or SUDAAN statistical software.
Many of the statistical methods used in this course are advanced, and may require consultation with a statistician. For modules 1822, it is required that you have the statistical knowledge of mixed effects models, and program knowledge of calling in SAS macros. Since Module 18 provides the background information for Modules 1922, it is advised that you carefully read Module 18 first before tackling other modules.
