Model trends, compare interventions, quantify risk and assess process performance with applied statistical tools.
Which calculator should I use?
Choose regression or curve fitting for relationships, moving averages for time-ordered data, and A/B testing for a planned comparison. Risk tables, control charts and reliability tools answer different operational questions; inspect their assumptions before interpreting results.
Available calculators
Linear Regression Calculator
Fit ordinary least squares with one or two predictors and inspect residuals.
Curve Fitting and Interpolation Calculator

Moving Average and Forecast Calculator
Smooth ordered data and show naive forward projections with observed residuals.
A/B Test Planning and Analysis Calculator
Plan equal-allocation conversion experiments or analyze a completed two-arm test.
2×2 Table, Odds Ratio, and Relative Risk Calculator
Compare event risks in exposed and comparison groups with odds and risk measures.
Control Chart and Process Capability Calculator
Build an individuals or fixed-size p chart and flag points beyond three-sigma limits.
Reliability and Failure-Rate Calculator
Compute exponential survival from constant hazard, or system reliability from independent components.
