The Pandas library is most commonly used for data manipulation and analysis, including the calculation of correlation matrices. Using the DataFrame.corr() method in Pandas, you can easily compute the correlation between numerical variables in your dataset. Correlation matrices are essential for understanding relationships between variables before building predictive models. Pandas offers efficient handling of large datasets and integrates well with other Python libraries for further analysis. Why Other Options Are Wrong : A) NumPy : While NumPy provides array manipulation functions, it does not have built-in functions for calculating correlation matrices. Pandas is preferred for this task. C) Matplotlib : Matplotlib is a plotting library and is not used for calculating statistical measures such as correlation. D) Seaborn : Seaborn is a visualization library built on top of Matplotlib, and while it can plot a correlation matrix, it does not directly compute the matrix itself. E) Scikit-learn : Scikit-learn is focused on machine learning algorithms and does not provide functions for calculating correlation matrices directly.
