Data Analyst

Project overview

In this project, you’ll take on the role of a data analyst tasked with exploring a dataset on westbound traffic on the I-94 Interstate highway. Applying skills in exploratory data visualization using Python libraries like pandas, Matplotlib, and Seaborn, you’ll analyze traffic volume data recorded by a station midway between Minneapolis and Saint Paul.

Your objective is to determine key indicators of heavy traffic on I-94, which could include weather type, time of day, or day of the week. By examining traffic volume patterns across various conditions, you’ll uncover insights to characterize peak congestion times on this busy highway. This project will strengthen your ability to combine and apply data visualization techniques to extract meaningful findings from real-world data.

Objective: Use exploratory data visualization to identify the primary factors contributing to heavy westbound traffic on I-94 based on weather, time, and day of week indicators.

“Dataquest starts at the most basic level, so a beginner can understand the concepts. I tried learning to code before, using Codecademy and Coursera. I struggled because I had no background in coding, and I was spending a lot of time Googling. Dataquest helped me actually learn.”
