Open original on YouTubeWhy selected: Selected because it explains the line-fitting idea behind the calculator's slope, intercept, and R-squared outputs.
What it adds: It supplements the least-squares formula by showing how a fitted line summarizes paired x-y data.
How to use it: Use the calculator to fit a line, then use the video to interpret slope, fit quality, and residual intuition.
