1. Relevant knowledge points and concepts:
Data mining is the process of discovering useful patterns, correlations, and models from large datasets. Core techniques include statistical analysis, machine learning (classification, regression), clustering, association-rule mining (e.g., Apriori), and pattern recognition. The goal can be descriptive (summarize data) or predictive (forecast outcomes based on learned models). Preprocessing (cleaning, transformation) and validation (cross-validation, significance testing) are essential parts of the workflow.

2. Step-by-step reasoning:
- The statement claims data mining “involves the extraction of hidden predictive information in large databases through statistical analysis.”
- “Extraction of hidden information” matches the concept of finding non-obvious patterns and relationships (e.g., customer segments, fraud signatures).
- “Predictive information” aligns with many data mining tasks (classification, regression, predictive modeling) aimed at forecasting future behavior or labels.
- “Large databases” is accurate because data mining methods are designed to work on big or complex datasets where manual inspection is impractical.
- “Through statistical analysis” is correct because statistical methods underpin most data mining techniques (probability models, hypothesis testing, regression, evaluation metrics), even when supplemented by algorithms from machine learning.

3. Calculations:
No numeric calculations are required for this conceptual true/false evaluation.

4. Why the correct answer is correct:
The statement captures the essence of data mining: uncovering hidden (latent) and often predictive patterns in large datasets, using statistical and algorithmic analyses to build models that predict or explain outcomes. Statistical analysis is a fundamental tool in that process.

5. Why the other option is incorrect:
“False” would imply the statement mischaracterizes data mining. It does not—rather it succinctly describes the primary purpose and methods used—so “False” is not supported.

6. Conclusion:
Therefore, the correct answer is True, which matches the provided answer.
