Measuring Price Change
This App developed in New Zealand, focuses on the CPI, working with price indices, change of base, time series in connection with the CPI, moving averages, trends, seasonality, and policy uses. The CPI is a measure used to adjust a timeseries for inflation. Price indices measure the rate of price change of goods and services over time, usually published as either monthly or quarterly change. They are official statistics published by National Statistics Offices. The history of price indices varies from country to country and there are a number of factors that can affect prices.
This Measuring Price Change app explains and has questions about using CPI. The black tabs on the left (information) and right (uses and calculations) would be useful for teaching economic based timeseries analysis.
