ITPEC FE Morning April 2020 — Question 77 of 80
Data Mining — discovering useful patterns and relationships in large volumes of data.
Data mining is the process of automatically searching large datasets to find hidden patterns, correlations, and trends that are not immediately obvious. It uses techniques from statistics, machine learning, and database systems.
Why not others:
- (a) Brainstorming — a group creativity technique for generating ideas, not related to data analysis
- (c) Decision tree — a specific classification/prediction tool that may be used in data mining, but is not the process itself
- (d) Document analysis — refers to analyzing documents for information, not the broad pattern-discovery process described
Key rule: Data mining = finding patterns in large data. It's the process, not a single tool or technique.
