There will be no lecture for this topic. The introduction to quantitative data analysis is very much covered by the parallel econometrics course. Here, I will point out only a coupe of specifics that may present a problem to researchers working with people data.

1. Coding. There is a higher chance that you will actually have to produce your data matrix either by transcribing paper-and-pen questionnaires to a computer or by setting codes for responses in some online questionnaire administration system or observation system. Please take note of the conventions about coding invalid responses, non-responses. Also, please be aware of the number of errors that may arise in such procedures.

2. Important correction. Sekaran & Bougie write on p. 276 that inconsistent responses may be edited by the researcher. This is NOT acceptable. There are  several reasons why a respondent may perceive his/her responses as consistent with respect to their understanding of the questions. Inconsistencies may be coded as invalid data but not "corrected to be consistent".
