Titanic Survival Analysis: Investigating Socioeconomic Factors
Research Question
What role, if any, did socioeconomic factors (passenger class, ticket fare, family size) play in determining survival outcomes for passengers aboard the RMS Titanic?
Project Overview
This project analyzes data from the 1912 RMS Titanic disaster to investigate how socioeconomic factors influenced passenger survival outcomes. Of the 2,224 passengers aboard, only approximately 700 survived, and this analysis seeks to understand the patterns behind these outcomes through a data-driven statistical approach.
The study encompasses three major components:
- Data Source Evaluation & Preparation - Evaluating multiple data sources (Stanford curated dataset, Wikipedia-extended data, British National Archives crew records) and selecting the most reliable source for statistical analysis; performing comprehensive data cleaning and preprocessing on 887 passenger records
- Exploratory Data Analysis - Investigating five key research questions about economic distribution, passenger class correlation with survival, ticket fare impacts, family size effects, and age group survival rates using advanced R visualization techniques
- Statistical Modeling - Developing and evaluating a logistic regression model for binary classification of survival outcomes using multiple predictors (passenger class, sex, fare, family size, age) to quantify the relative impact of socioeconomic variables
The project demonstrates rigorous statistical methodology including data source evaluation, exploratory analysis with hypothesis testing, and predictive modeling using R. Key findings reveal clear socioeconomic patterns in survival outcomes, with passenger class and ticket fare showing significant correlations with survival probability.
