Plots, smoothing plots such as PROC LOESS and PROC PRINCOMP help detect outliers. If there is a sound reason why the data point should be disregarded then the outlier may be deleted form analysis.

Since the data size of the official statistical surveys tends to be large, the editing bounds are often prepared in advance using the previous survey data in which outliers are inevitable. Under ordinary circumstances, outliers may not be properly

Tips and Tricks for Analyzing Non-Normal Data
www.qualitymag.comThis article will cover various methods for detecting non-normal data, and will review valuable tips and tricks for analyzing non-normal data when you have it. The 10 data points graphed here were sampled from a normal distribution, yet the histogram appears to be skewed. Helpful hint: Avoid histograms for small sample sizes.
