What Are the Key Steps in Data Science? 

Data Collection 

Collect the Right Data

Pull data from websites, APIs, databases, sensors, or social media. Reliable data sources fuel every successful project.

Data Cleaning 

Clean the Messy Data 

Remove duplicates, handle missing values, and fix errors. This step can take up to 80% of a data scientist’s time. 

Data Analysis 

Analyze the Data 

Use statistical techniques to find patterns, trends, and correlations. Turn numbers into meaningful stories. 

Model Building 

Build Machine Learning Models 

Use algorithms like Linear Regression, Decision Trees, or Neural Networks to predict future outcomes. 

Interpret & Communicate 

Present the Insights 

Use dashboards, charts, or storytelling to share findings with stakeholders. Help teams make data-driven decisions.
