Importance of good quality data and DATA ANALYSIS for Research Methods INTRODUCTION Conducting a survey is often a useful way of finding something out‚ especially when `human factors ’ are under investigation. Although surveys often investigate subjective issues‚ a well-designed survey should produce quantitative‚ rather than qualitative‚ results. That is‚ the results should be expressed numerically‚ and be capable of rigorous analysis. The data obtained from a study may or
