IMHO, this book should be mandatory for anyone who creates or uses statistical analyses. It was originally written in the early 1950's, but is probably even more valid today than then. As noted, any kind of statistical analysis can be distorted (willfully or otherwise), whether tabular, graphical, or whatever. Both the analyst and the interpreter have to know exactly what the objective is.
