Symmetric, LongTailed Histogram  
Description of LongTailed 
The above is a histogram of
the DZIUBA1.DAT data set.
The previous example contains a discussion of the distinction between shorttailed, moderatetailed, and longtailed distributions. In terms of tail length, the histogram shown above would be characteristic of a "longtailed" distribution. 

Recommended Next Step  If the histogram indicates a symmetric, long tailed distribution, the recommended next step is to do a Cauchy probability plot. If the Cauchy probability plot is linear, then the Cauchy distribution is an appropriate model for the data. Alternatively, a Tukey Lambda PPCC plot may provide insight into a suitable distributional model for the data.
