A Graph is Worth 1000 Words (n=15, P=.6)

Many beginning consultants -- especially those recently graduated from top economics, math, and engineering programs -- do not know how to effectively guide clients using statistics. They have read Kotter, Tufte, Block, Minto, and Porter, but few have read Huff's timeless 1954 classic, How to Lie With Statistics. A beginning playbook might read as follows.
-Omit sample size, confidence, and any greeks ("The blindfolded leading the blind.")
-Sample high, but use a flawed methodology to drive action from biased conclusions ("Measure with a micrometer, mark with a crayon, cut with an axe.")
-Sample low, or at least sub-sample until the means tell an insightful story ("Throw it against the wall and see what sticks. Okay, throw it again.")
But let us not focus on lies; let us focus on truths, if only for a moment in the workday. Over my six years in consulting and eight combined months of experience in [your industry], I have found these four graphs unusally helpful for communicating a few difficult but common messages. Today I elect to share this $920 of billable work with you for free.
