Water Quality Explanatory Data Analysis

Overview

This project focuses on analyzing water quality data using various statistical and machine learning techniques. The primary objectives include bivariate and multivariate data analysis, correlation analysis, data preprocessing, and modeling using Decision Tree and Random Forest Classifiers.

What You Will Learn

  1. Bivariate and Multivariate Data Analysis: Explore relationships between different variables in the dataset.
  2. Correlation Analysis: Understand how different features are related to each other.
  3. Data Preprocessing:
    • Handling missing values.
    • Splitting the data into training and testing sets.
    • Normalizing the data for better model performance.
  4. Modeling:
    • Implementing Decision Tree and Random Forest classifiers to predict water quality.
    • Visualizing the Decision Tree to interpret model decisions.
