Quizplus · Accepted Answer

The consumer price index (CPI) measures the total cost of a specific market basket of consumer goods and services. This market basket includes a variety of goods and services typically purchased by urban consumers, such as food, housing, transportation, and medical care. By tracking changes in the prices of these goods and services over time, the CPI provides a way to measure inflation and changes in the cost of living.
