This repository contains an experimental study designed to analyze the impact of LinkedIn Premium subscription on job search success rate through A/B testing and hypothesis testing. Additionally, the study examines the correlation between networking activity on LinkedIn and job success rate.
The study aimed to answer the following questions:
- Is there a significant association between having a LinkedIn Premium subscription increase a user's job search success rate through LinkedIn?
- Is there a significant association between networking activity on LinkedIn and job success rate?
- Independent Samples T-Test Analysis: Conducted to compare job success rates between LinkedIn Premium users and non-Premium users.
- Correlation Analysis: Evaluated the relationship between networking activity (e.g., connections, messages) and job search success.
- Tools Used: IBM SPSS for statistical tests, power analysis and results interpretation.
-
