Statistics in Motion

The Empirical Rule

For a normal distribution, roughly 68% of data falls within ±1σ, 95% within ±2σ, and 99.7% within ±3σ. Watch it hold across fresh random samples — drawn every 6 seconds.

Within ±1σ — theory · 68.27%

Within ±2σ — theory · 95.45%

Within ±3σ — theory · 99.73%

μ = 0.00 · σ = 1.00 · N = 1,000 samples drawn via Box–Muller

The C.E.I.A. Charter

Four principles that govern the work.

Human-centered data science education and responsible AI communication.

❤️

Compassion

Humanity at the Center

We teach with respect for human stories — keeping the work people-first, ensuring technology serves communities and not the other way around.

⚡

Excellence

Rigor with Humility

Rigorous thinking paired with curiosity — clarity in teaching, precision in analysis, integrity in method. Continuous refinement of craft.

✓

Integrity

Truth as Foundation

Honesty with data, clarity in method, intellectual humility — acknowledging limits, citing sources, honoring trust. Knowledge built to endure.

🔓

Accessibility

Knowledge Without Gates

Data science belongs to everyone — especially communities long excluded. Clarity that empowers, not simplicity that condescends.

Data is truth's language — ethics and transparency, its grammar.

Grounded in Ethics. Built for Impact.

PyStatR+ brings together rigorous data science, ethical AI, and human-centered education for institutions, founders, and educators across South Sudan, East Africa, and the diaspora.
