My personal street cred: Welcome to some of basic statistics information presented differently. If you don't get it one way, via our happy flowchart approach, another way may do. And the other way is presenting the very same stats information from a different perspective. And if that doesn't work, we try yet a third way. In short, you do your best; we will too. Together, we practitioners will get 'er done -- one way or another! This Hedbring Stats Guide is not exhaustive. It in fact is anything but complete. I am not a full bottle on stats. LOL, compared to many of my stat-centric colleagues, it might even be argued that I am running on fumes. Nonetheless, I really believe practitioners will benefit from my efforts to re-bottle old wine to make it look, smell, and hopefully taste a whole lot better than before. I sure do hope so. My personal street cred begins 40 years(!) ago as a student at Northwestern University. As an economics major, I and my fellow students had to write our own stat programs. If we needed standard deviation data, Fortran IV was our assistance, not SPSS or myriad online formula-driven calculators. The slide ruler was our savior, not the web. If we wanted to test a group against the world, our main task was to write the t-test software to get it done. Back then we all learned our lessons well. Years later when writing a federal research grant to fund my doctoral dissertation at Columbia University, determining the appropriate statistics was a mere trifle. And stat-based software -- SPSS, BBMD, APA -- proved no challenge. We took our stat coursework and those of us older grad students enjoyed the review. True, our dissertation committees and reviewers from major research journals were challenges -- but never an obstacle. We got it done. My cred ends with several successful publications plus award-winning software. These days, too many students seem not to have a clue -- or they suffer short memories. Too many cannot understand when to use and when to avoid, say, a t-test, z-test, chi-square, or ANOVA, let alone write even the most basic stat software (such as standard deviation calculation). The Hedbring Stat Guide tries to help.
