UK Annual Population Survey Analysis (2021)

Project Overview: A statistical analysis of the UK Annual Population Survey (APS) dataset to explore relationships between [Variable A] and [Variable B], accounting for survey response bias.

🎯 Objectives

• Data Cleaning: Recoded complex categorical variables for meaningful analysis.
• Statistical Testing: Implemented Chi-Square tests to determine the significance of the relationship between [Variable A] and [Variable B].
• Bias Correction: Applied survey reweighting techniques to account for non-random response bias and missing data.
• Visualization: Created publication-standard plots using ggplot2.

🛠 Techniques Used

• Univariate & Bivariate Analysis
• Hypothesis Testing (Chi-Square)
• Confidence Intervals & Reweighting
• Multidimensional Analysis (3-way cross-tabulation)
