Reciprocal Evolution and Base 100 Index
This page introduces advanced concepts in statistical calculations, including reciprocal evolution and the base 100 index, which are essential for statistique terminale exercice corrigé (corrected terminal-level statistical exercises).
The document explains reciprocal evolution, which is the evolution rate from a final value back to an initial value. This concept is particularly useful in financial calculations and economic analyses.
Example: If a store's sales increase by 8%, the reciprocal evolution to return to the original value would be a decrease of approximately 7.41% (1 / 1.08 ≈ 0.9259).
The page then introduces the base 100 index, a crucial concept in economics and statistics for comparing values over time.
Example: Using a base 100 index for the year 2000, the document shows how to calculate and interpret index values for subsequent years, demonstrating changes in a company's turnover.
The guide provides detailed examples of how to use the base 100 index to calculate evolution rates between different years and how to determine actual values from index numbers.
Example: Given an index of 116 for 2019 and a turnover of €45,000, the document shows how to calculate the turnover for 2017 when the index was 100.
Highlight: Understanding the base 100 index and how to interpret it is crucial for analyzing long-term economic trends and performing exercice statistique seconde Bac Pro avec corrigé (corrected second-year Bac Pro statistical exercises).
This page reinforces the importance of mastering these advanced statistical concepts for students preparing for higher-level mathematics and economics courses.
