🔍 Overview

This project performs a simple linear regression analysis on advertising data to predict sales based on different advertising channels. Using Python and Jupyter Notebook, the project walks through data exploration, visualization, model building, and evaluation. It serves as a straightforward introduction to regression techniques and how they can be used for predictive analytics.

✨ Project Highlights

• Data Exploration:
  Perform exploratory data analysis (EDA) to understand the distribution of advertising spend and sales.

• Visualization:
  Generate scatter plots and regression lines to visualize relationships between variables.

• Model Building:
  Fit a simple linear regression model to predict sales from advertising spend (e.g., TV, Radio, Newspaper).

• Evaluation:
  Evaluate the model's performance using metrics such as R² and Mean Squared Error (MSE).

---

📊 Dataset Description

• File: advertising.csv
• Contents:
  The dataset includes advertising spending and corresponding sales data. Common features include:
  • TV: Advertising dollars spent on TV.
  • Radio: Advertising dollars spent on radio.
  • Newspaper: Advertising dollars spent on newspapers.
  • Sales: Sales generated (dependent variable).
• Format: CSV file with rows representing individual observations.
