Description
🔍 Explore
Place data points on a graph and test how well different polynomial curves describe them.
🎮 Try It
Drag points from the data bucket or use Add point. Compare linear, quadratic and cubic best fits, then show residuals. Choose Adjustable to move the coefficient sliders and shape the curve yourself.
🎯 Your Mission
Arrange at least five points so a quadratic fit matches them better than a linear fit. Use the residuals and fit readouts as evidence without making every point identical to the curve.
🌍 Real-World Connection
Curve fitting helps scientists model trends in experimental measurements.
