One Line Splits Two Groups

Sometimes you want to split data into two groups. For example into blue and red.

The computer draws a straight line for that. All the blue dots should land on one side, all the red ones on the other.

How It Works

  1. Show the Data

    Put all your data points on a graph.

  2. Draw Line

    Draw a straight line through the data.

  3. Check Separation

    See if the line correctly separates the groups.

  4. Adjust

    Move the line. It should split the groups as well as possible.

Can you find the perfect line?

Guess first, then experiment

Can every group of data be separated with a single straight line?
