Situation
Â
- This project involved conducting Exploratory Data Analysis (EDA) and data cleaning on an automobile dataset to prepare it for machine learning applications. The dataset included various car features such as make, model, year, mileage, fuel type, and price.
- The objective was to uncover trends and patterns in car pricing and performance to support predictive modeling and data-driven insights for market analysis.
Task
- My role was to act as a Data Analyst, exploring and preprocessing the data to ensure its readiness for machine learning models.
- I was responsible for identifying data quality issues, uncovering insights through visualization, and preparing clean datasets for future predictive analysis.
Action
- I loaded the dataset and performed thorough data cleaning, handling missing values, removing duplicates, and converting data types.
- I conducted exploratory analysis using visualization libraries to analyze trends and relationships between car features and pricing.
- I created pivot tables and correlation heatmaps to highlight feature importance.
- Advanced preprocessing steps like encoding categorical variables and scaling numerical data were implemented to prepare for model training.
Result
- The analysis revealed key insights, such as how mileage, fuel type, and manufacturing year impact car pricing.
- The cleaned and processed dataset is now ready for machine learning models to predict car prices accurately.
- This work laid the foundation for building predictive models and informed strategies for car pricing and marketing.
Reflection
- Through this project, I strengthened my skills in data cleaning, visualization, and exploratory analysis using Python libraries like Pandas, Matplotlib, and Seaborn.
- If I had more time, I would apply machine learning models to predict car prices and validate the effectiveness of the features identified during EDA.
- My advice for similar projects is to prioritize data quality and use visualizations to uncover hidden patterns for more impactful insights.
