Page 2: Reference Indices and Their Applications
The second page delves into the concept of indices and their relationship with multiplier coefficients. It explains how indices are calculated relative to a reference year and their interpretation.
Definition: An index is calculated by comparing values to a reference year, with the base year typically set at 100.
Example: When an index result is greater than 100, it indicates an increase compared to the reference year; less than 100 indicates a decrease.
Highlight: The relationship between indices and variation rates is demonstrated through the formula: Variation Rate = [(Index/100) - 1] × 100.
Vocabulary: The reference year (année de référence) serves as the baseline for index calculations, typically assigned a value of 100.
