Choose the correct answer from the options given below:
Solution
Statements A, B and D correctly describe time series analysis: extracting characteristics, forecasting, and studying components.
Statement C denies that conclusions are drawn from systematically arranged data, which contradicts the purpose of the technique.
Hence only C fails to specify the concept.
