Understanding CPI and Inflation

The video tutorial explains the Consumer Price Index (CPI) and its role in measuring the cost of a typical basket of goods in Jacksonia. It provides a step-by-step guide to calculating the CPI for 2015 and 2017 using 2016 as the base year, and determining the inflation rates between these years.
