P.310 Technology Project- Assessing Normality

This project involves using STATDISK for assessing the normality of data sets. If STATDISK has not yet been used, it can be installed from the CD included with this book. Click on the Software folder, select STATDISK, and proceed to install STATDISK. The data sets in Appendix B are available by clicking on Datasets on the top menu bar, then selecting the textbook you are using. STATDISK can be used to assess normality of a sample by clicking on Data and selecting the menu item of Normality Assessment. Use this feature to find a sample that is clearly from a normally distributed population. Also find a sec-ond sample that is clearly not from a normally distributed population. Finally, find a third sample that can be considered to be from a normally distributed population if we interpret the requirements loosely, but not too strictly. In each case, obtain a printout of the Normality Assessment display and write a brief explanation justifying your choice.
