Scatter Plot Calculator - Plot X Y Data Points Fast
A sophisticated scatter plot calculator became crucial during my research on machine learning algorithm performance. I was analyzing the relationship between training dataset size and model accuracy across hundreds of experiments, and I needed to visualize correlation patterns quickly. Without this advanced statistical tool, calculating Pearson correlation coefficients and identifying data trends would have required complex statistical software and extensive manual analysis.
This comprehensive correlation analysis tool transforms paired numerical data into interactive visualizations with complete statistical analysis. Whether you're conducting scientific research, analyzing business metrics, or studying variable relationships, this calculator provides professional-grade scatter plot analysis with correlation coefficients and statistical insights.
Formulas and Worked Example
Pearson correlation (r): r = Sxy / sqrt(Sxx · Syy), where Sxx = Σ(x − x̄)², Syy = Σ(y − ȳ)², and Sxy = Σ(x − x̄)(y − ȳ).
Best‑fit line (least squares): y = a + b x with slope b = Sxy / Sxx and intercept a = ȳ − b·x̄. When forcing through origin, b = Σ(xy)/Σ(x²) and a = 0.
Example: For points (1,2), (2,4), (3,6), x̄ = 2, ȳ = 4, Sxx = 2, Syy = 8, Sxy = 4 → r = 4/√(2·8) = 1, and y = 0 + 2x.
