About Karen Grace-Martin

Karen Grace-MartinKaren Grace-Martin, the founder and president of The Analysis Factor, is a professional statistical consultant with Masters degrees in both applied statistics and social psychology.

Her career started in psychology research, where her frustration in applying statistics to her data led her to learn more statistics.  She soon realized that her favorite part of research was data analysis, leading to a career change.  Her background in experimental research and working with real data has been invaluable in understanding the challenges that researchers face in using statistics.

Karen was a professional statistical consultant at Cornell University for seven years before founding The Analysis Factor.  Karen has worked with clients from undergraduate honors students on their first research project to tenured Ivy League professors, as well as non-profits and businesses.  Her ability to understand what researchers need and to explain technical information at the level of the researcher’s understanding has been one of her strongest assets as a consultant. She treats all clients with respect, and derives genuine satisfaction from the relief she hears in their voices when they realize that someone can help them.

Before consulting, Karen taught statistics courses for economics, psychology, and sociology majors at the University of California, Santa Barbara and Santa Barbara City College.  She has co-written an introductory statistics textbook with Stephen Sweet: Data Analysis with SPSS.  Karen has developed and presented many statistics workshops, most recently on missing data, logistic regression, and interpreting regression parameters.
