- You have lots of dots on a piece of paper, each dot representing two things (like car size and speed).
- The “best friend line” wants to be close to as many dots as possible, like a good friend who sticks by you!
- It adjusts itself up and down, tilting left or right, trying to find the best fit for all the dots.
- Once it finds that “best friend line,” you can use it to guess how fast a new, unseen car might go based on its size!
The “best friend line” in Linear Regression is actually an equation, but you don’t need to worry about that yet. Just remember, it helps us understand how two things might be related by finding a line that fits them best!
Here are some things to keep in mind:
- The “best friend line” isn’t always perfect. Sometimes, dots might be far away from it, like a friend having a bad day. But it’s still the best fit overall!
- This is just a simple explanation, and there’s more to Linear Regression in the grown-up world. But hopefully, it gives you a basic idea of how it works!
So, the next time you see dots on a graph, remember, there might be a “best friend line” waiting to be discovered!
