When outliers are discovered, should they always be removed from the data set before further analysis?
Step 1 of 5) When outliers are discovered, should they always be removed from the data set before further analysis The wording of questions can significantly affect the responses and, therefore, the validity of a study. A great source for phrasing survey questions is Saris, W. E. and Gallhofer, I. N. (2007) Design, Evaluation, and Analysis of Questionnaires for Survey Research. Hoboken, NJ: Wiley. For those respondents who presented with question A, 21.4% gave “yes” responses, while for those given question B, 47.8% gave “no” responses. The conclusion you may arrive at is that most people are not willing to forbid something, but more people are willing not to allow something. These results illustrate how wording a question can alter a survey’s outcome.
