If doing a quantitative study:
Identify the data sources or instrumentation for each of the variables in your study. Justify the use of each data source or instrument in your study. Support your justification with citations from peer-reviewed sources. Discuss the reliability and validity of each data source or instrument. Also discuss how the instrument is scored and the level (categorical, ordinal, interval, ratio) the data obtained for your variable of interest.
