Statistics Calculators
Paste datasets to calculate descriptive statistics, sample/population spread and weighted averages with the formulas, conventions and row-level working kept visible.
Open a real interactive tool instead of landing on a thin keyword page.
Formulas, units and assumptions stay visible beside the result.
Move between genuinely different calculations inside one collection.
Supplier, manufacturer, drawing and standards data remain authoritative where required.
Choose the calculation that matches the job
Each page owns a distinct input/output task. Reciprocal forms stay together when the underlying job is the same.
Calculator
Statistics Calculator — Mean, Median, Mode, Quartiles, Variance & Standard Deviation
Paste a dataset and calculate count, sum, mean, median, modes, min/max/range, Tukey quartiles, IQR, sample/population variance and standard deviation, standard error, coefficient of variation, skewness, excess kurtosis, outlier fences and a frequency table.
Open calculatorCalculator
Standard Deviation Calculator — Sample & Population Variance with Steps
Calculate sample or population standard deviation from pasted data with mean, variance, squared-deviation sum, standard error, coefficient of variation, Tukey outliers and a row-by-row deviation and z-score table.
Open calculatorCalculator
Weighted Average Calculator — Values, Weights, Contributions & Plain Average
Paste value-and-weight rows to calculate the weighted mean, weighted sum, total weight, plain average, weighting shift and each row’s normalized weight percentage, product and contribution, without requiring weights to total 100.

Formula first, assumptions visible
MAXScanner keeps editable rates and dimensions next to the result, shows the working where it helps, and avoids turning reciprocal formulas into duplicate pages. For product, electrical or construction decisions, manufacturer data, drawings and applicable standards remain authoritative.
