In 2012, the Federal Reserve announced an inflation objective of 2 percent “over the longer run” for the price index of personal consumption expenditures (FRED code: PCEPI).

Plot the percent change from a year ago for both inflation measures since 2000. Download the data and compute the averages and standard deviations over that period. What do you conclude?
