Screen Time Impact on Adolescent Wellbeing

The problem

Screen time and adolescent wellbeing is a topic full of strong opinions and thin evidence — the question was whether a real relationship shows up once the data is actually modelled, not just eyeballed.

The approach

• →Cleaned and pre-processed a dataset of 98,000+ adolescent records
• →Ran exploratory data analysis and visualisation in Seaborn and Matplotlib to surface patterns before modelling
• →Fit a linear regression model relating screen time to mental-health indicators, evaluated with R² and MSE
• →Translated the statistical output into plain-language findings a non-technical reader could act on
