💡 Regression — Predicting Numbers
Regression is used when you want to predict a continuous value (a number).
👉 Think: “How much?” or “How many?”
👀 Visual Idea
Imagine dots on a chart (data points), and the model draws a line through them to predict new values.
The line helps estimate:
“If the house is this big → what’s the price?”
