W. Young, Professor of Psychometrics at the University of
North Carolina at Chapel Hill, received his PhD in Psychometrics
from the University of Southern California in 1967. He has
been on the faculty of UNC-CH ever since.
Young's teaching interests focus on "Seeing what your
data seem to say". This visually intuitive approach to
statistics helps to clarify the meaning of data. His courses,
ranging from his introductory undergraduate course on Psychological
Statistics, to his advanced graduate courses on Data Analysis,
Visualization and Exploration, reflect this focus.

need to make an intensive effort to understand your data:
Rather, your computer makes intensive calculations so that
the data can be shown to you in a visually comprehensible

development project, have created ViSta, a visual statistics

is based not only on Prof. Young's theory-based approach to
data analysis, but also on his 30-year career in computational
and graphical statistics.
Young's early research interests focused on Multidimensional
and Nonlinear Multivariate Data Analysis (for which he was
elected the President of the Psychometric Society, and received
the American Market Research Association's O'Dell award, both
in 1981). Via these research interests, Prof. Young became
involved in software development early in his career.
Young has served as a professional consultant on statistical
system interface design with SAS Institute, Statistical Sciences
(the S-Plus system), and BMDP Inc. He has written or designed
data analysis modules for the SAS, SPSS and IMSL systems.
He is a member of the American Statistical Association's sections
on Computational and Graphical Statistics.
