Biostatistics is EASY!!

The USMLE biostatistics workbook caters to USMLE examinees, medical specialists, nurses, physicians, researchers, and others who require only a refresher of the topics and topic-concepts. Unless you're pursuing a degree in biostatistics at the university, high yield biostatistic concepts are fairly straight-forward.

The Workbook covers over 50 topics in 19 chapters* and is filled with many colorized graphs, colorized tables & other pics that take students through a problem step-by-step.  Details are below.  The Workbook’s tricks, tips & shortcuts helped my wife & others understand exactly what to do.  However, the Workbook is designed so that you can work on the word-problems exclusively and NOT read any of my tricks, tips & shortcuts. It’s totally up to you.  You’re the boss!!

TOTALLY intuitive tricks, tips & shortcuts for biostats – you'll never forget them!

The Workbook has another design to help the reader!:  each problem I have you solve is written as a vignette that’s loaded with key concepts of a specific disease AND it’s written so you can choose to read the vignettes about diseases and then solve the biostat problem or, SKIP the vignettes and go straight to solving the problem.  

Different people have different styles of learning and wanted more or less of all the features I described.  So the Workbook is designed to accommodate everyone; I advise that you read, at least once, the key tips, keywords, a break-down of the math, and the steps I provide on how to solve each topic.  But you don’t have to!!!

The USMLE biostatistics workbook is LOADED with features…

Each chapter provides
a point-blank overview of what you need to know (what’s high yield and why) and  the keywords that flag which
  topic you are being tested on.  Typically only one page long, it will include a break-down of the formula (the math)
  you need to know.  These are the key tricks, tips & shortcuts necessary to make high yield biostatistic topics easy to
  recognize, interpret & solve.
many colorized visual and graphic aids; the double hump is explained in four steps where the core concept of each
  step is colorized. Virtually all topics are explained by richly colored graphs, tables & other pics.
about nine biostatistic problems with answers that thoroughly explain how to arrive at the answer – re-enforcing
  lessons learned in the overview, showing how the examiner could “tripped-up” the examinee,  and how to
  fool-proof yourself!
a one page doc of all the chapter-topic’s key concepts, in large font & colorized, that you print & hang on the wall!!!
additional information such as links to quality web sites that provides additional quality problems for you to solve,
  on-line calculators, concise discussions that explore a topic more deeply and/or, additional explanation/s about
  the chapter-topic/s.

Double hump

Renamed to "double chump," I guarantee that this seemingly troublesome test question will become completely intuitive and absolutely NO trouble.
