COVID 19 Data Exploration

My Comprehensive COVID-19 Data Exploration Project is a robust and insightful analysis conducted entirely using SQL. This project aims to provide a detailed exploration of COVID-19 data, enabling users to gain valuable insights and make data-driven decisions in the face of the pandemic.

Data Cleaning in SQL

In this project, I leveraged the power of SQL Server to transform raw housing data into a more usable format for analysis. By utilizing SQL queries, I cleaned, formatted, and structured the data to ensure consistency and integrity, enabling meaningful insights and analysis.

COVID 19 Tableau Dashboard

Continuing the COVID-19 data exploration journey and leveraging the power of Tableau's visual analytics, I unraveled global insights such as infection rates, total deaths per continent, percent population infected, and percent population infected per country.

Excel Bikes Sales Dataset Project

In my Excel data analysis project, I took bike sales data, cleaned and organized it, and created a dynamic dashboard using Excel. The dashboard includes filters, interactive visualizations, such as graphs and charts, showcasing average income per purchase and customer age brackets.
