Reader rsm is perpetually concerned about the precision of economic data, most recently here in re: gasoline prices.
Why am I paying 12-15% more than the graph? What possible reason do you have for not including standard errors? Would error bars stop you from making all these claims about noise?
Below is the price of regular gasoline, plus/minus 1.96 standard errors.

In my view, reporting of standard error bands does not change one’s views regarding the course of gasoline prices.
Note that the webpage for these data comes up in a google search first time around when one puts in search words “gasoline” “standard error” “energy information”…
