Why Statistics ?

Statistics is fundamentally about making sense of uncertainty and variability in the world around us. Here's why it's so important:

• Make informed decisions based on evidence rather than guesswork
• Understand trends and patterns in large amounts of information
• Predict future outcomes based on past data
• Communicate findings clearly to others

In simple, statistics is like having a smart tool that helps you understand messy, confusing information and turn it into useful knowledge you can actually use.
