I remember the title of a math book we had in MAT 118 (DESCRIPTIVE
STATISTICS) at Parkland College was titled:
"How to lie with statistics"
It went into how you can use just about any statistics available (almost)
and then make any case-in-point based on those statistics by choosing the
proper way to show the stats and calculate one of several different kinds
of averages (mean, median, etc.).
