Show answer and explanation
Correct answers: A, B, D, E
Explanation
To extract insights from large datasets, a combination of data visualization, advanced algorithms like clustering and classification, and proper data preprocessing is required. Manual inspection is not viable for large datasets, but automated and systematic approaches ensure the data is prepared for analysis and insights are actionable.
- A. Correct.
Data visualization techniques are critical for identifying trends, outliers, and patterns in a large dataset, making it easier to derive insights.
- B. Correct.
Clustering algorithms are effective for grouping customers based on similar characteristics, which is valuable for targeted marketing strategies.
- C. Incorrect.
Manually inspecting the dataset row by row is impractical and inefficient for large datasets, and won't extract meaningful insights at scale.
- D. Correct.
A classification model can use historical data to predict future behaviors, making it a powerful tool for actionable insights.
- E. Correct.
Data cleaning and preprocessing are foundational steps to ensure the dataset is reliable and accurate for further analysis, including data mining and modeling.
