Document Summary

The concepts included in this notes are the ones that i get wrong and they are very tricky!! Understand the difference between likert scale and graphing continuum. He doesn"t ask much in the sample midterm so i don"t think there s a need to worry about it. Remember the major steps of setting a survey: 1) what should be asked, 2) the layout, 3) and finishing and refining questionnaire. In an observation study, you can observe physical behavior and characteristics, but definitely. Not cognitive process (no one can do mind reading!!) Observational research is less likely to have social desirability bias than survey research (that"s why observational research is preferred to questionnaire/survey research!) Reason: you can have biased wordings in a questionnaire! For observation, you can have greater control ( if it is contrived) or even rely on machinery for observation! Main difference between human vs machine observation. Definition of contrived: artificial, physiological measure, control extraneous factors.
