Statistics Notebook Templates — Distributions, Z-Scores, Confidence Intervals

Statistics templates are designed for quick probability and inference checks. They use built‑in distribution functions like normalcdf, binompmf, and tcdf (educational use).

Statistics templates

• Binomial Distribution (PMF/CDF/Inverse) — Notebook Template — Compute binomial probabilities for k successes in n trials with success probability p. Includes PMF, CDF, and inverse.
• Confidence Interval for a Mean (t-based) — Notebook Template — Compute a t-based confidence interval for a sample mean when σ is unknown (educational). Includes margin of error and assumptions.
• Normal Distribution Toolkit (PDF/CDF/Inverse) — Notebook Template — Compute normal PDF, CDF, and inverse CDF (quantiles) with documented parameters. Great for z-scores and percentiles.
• Poisson Distribution (PMF/CDF) — Notebook Template — Model counts with a Poisson rate λ: compute probabilities and cumulative probabilities for events.
• Regression Lab (Linear + Quadratic) — Paste (x,y) points, fit models, inspect R², and plot alongside data.
• t Distribution (CDF/Inverse Critical Values) — Notebook Template — Compute t CDF values and critical t quantiles for confidence intervals and hypothesis tests (educational).
• Z-Score + Percentile (Normal Approximation) — Notebook Template — Standardize a value, compute its percentile (normal assumption), and document whether the assumption is reasonable.
