Data Science for Beginners

Data Science is the art of extracting meaningful insights from raw data. It combines mathematics, programming, and domain expertise to solve complex problems.

2. Data Science Lifecycle

Data science follows a structured path: Collection, Cleaning, Exploration, Modeling, and Deployment.

Real-world data is often messy. Cleaning alone can take up to 80% of a data scientist's time!

9. Python for Data Science

Python is the leading language for data science due to its rich ecosystem of libraries.

import pandas as pd

# Creating a simple dataset
df = pd.DataFrame({
    'Metric': ['Revenue', 'Users', 'Profit'],
    'Value': [15000, 450, 4200]
})

print(df.describe())
