Weighted pricing is necessary to measure the effect of individual unit price changes on the economy's overall inflation. The consumer price index, for example, uses data collected by surveying households to determine what proportion of the typical consumer's overall spending is spent on specific goods and services, and weights the average ...
A CPI is a statistical estimate constructed using the prices of a sample of representative items whose prices are collected periodically.

The U.S. Department of Labor's Bureau of Labor Statistics (BLS) explains the differences: The CPI frequently is called a cost-of-living index, but it differs in important ways from a complete cost-of-living measure.
