Back when I was on the "speaking circuit" in the direct response biz, I taught a class for a couple associations on "Direct Marketing Math and Measurement". And while this page is meant to stay very separate from partisan politics, I did catch a very misleading use of math when it comes to the increase in gas prices.
The current governor of California accurately claimed that, per the Persian Gulf conflict, gas prices in California have risen 32%, compared to, among other states, Indiana where prices have gone up around 69%.
One of the basic concepts I emphasized in my class was the difference between absolute (numeric) and relative (percentage) measurement. (Not so helpful illustration below!)
The current average price of a gallon of gas in California is $6.15. The same gallon is $4.09 in Indiana. An "absolute" difference of $2.06.
Meaning, before the rise, California's gas was an average of $4.66, compared to Indiana's $2.43. An absolute difference of $2.23.
So - Indiana's gas has risen 17 cents more than California since the start of the conflict. Which sounds a little less dramatic than the 70% vs. 32% rise promoted by the California governor.
A cautionary tale when you see claims touting percentage differences where the start / end real numbers are more hidden.
Taking it one more step, if you have a car with a 15-gallon tank and fill it up once a week in California for a year at today's prices, that will cost you almost $4,800. In Indiana, that same amount of gas will cost you almost $3,200.
For that $1,600 dollars, maybe the Indiana folks can take a trip to California. Or maybe Florida. Or even Vegas, but then that's a whole other discussion on odds, percentages and real numbers. Perhaps a subject for the next post....
