FISHER’S IDEAL INDEX (VOLUME)

Statistics Directorate    
French Equivalent: Indice idéal de Fisher (de volume)

Definition:
Fisher’s Ideal volume index is the geometric mean of the Laspeyres and Paasche volume indices.

Context:
A measure of change in volume from period to period. It is calculated as the geometric mean of a chain Paasche volume index and a chain Laspeyres volume index. In other words, it is an average of two distinct measures of change in volume: one calculated as if prices were constant in the first of two adjacent periods (Laspeyres volume) and the other calculated as if prices were constant in the second of the two adjacent periods (Paasche volume) - (Chain Fisher Volume Index, Glossary - Statistics Canada.
