Normal Distribution Curve Explained - Standard Deviation Visualization #3024529 (License: Personal Use)

This image depicts a standard normal distribution (Gaussian curve) centered at X, with vertical lines marking integer standard deviations (-3σ to +3σ). The shaded purple regions highlight the empirical rule: ~68% of data falls within ±1σ, ~95% within ±2σ, and ~99.7% within ±3σ. The curve is symmetric and smooth, ideal for teaching statistical concepts.

Used in educational content, statistics tutorials, data science blogs, and academic presentations to explain probability distributions, z-scores, and confidence intervals. Matches user intent for learning or visualizing foundational statistical principles.
