Summarize a numerical sample
Mean Calculator finds the arithmetic average. Median Calculator finds the middle of the sorted values. Compare them when extreme observations pull the average away from typical values. Sample Standard Deviation Calculator measures sample spread using n − 1. Do not treat its result as population standard deviation.
- Mean CalculatorCalculate the arithmetic mean of decimal numbers. Separate values with commas, spaces, semicolons, or new lines.
- Median CalculatorFind the median of an unsorted number list. Odd counts return the middle value; even counts average the middle two. Negative values are supported.
- Sample Standard Deviation CalculatorCalculate sample standard deviation, variance, mean, and standard error of the mean. Inspect the n minus 1 denominator and sample count.
Work with sets, integer bases, or polynomials
Cartesian Product Calculator combines choices across sets. Power Set Calculator lists subsets of one set. Check delimiters before requesting either expansion. Decimal, Hex, Binary and Octal Converter changes integer notation. Polynomial Long and Synthetic Division Calculator returns a quotient and remainder. Use the polynomial input syntax instead of entering an ordinary fraction.
- Cartesian Product CalculatorList every combination from two or more sets, such as sizes × colors. Enter one comma-separated set per line.
- Power Set CalculatorList every subset of up to 13 items, including the empty set. A set of n items gives 2ⁿ subsets, one per line.
- Decimal, Hex, Binary and Octal ConverterConvert decimal to hex, hex to decimal, binary, or octal. Preserve large integer precision and convert signed numbers directly in your browser.
- Polynomial Long and Synthetic Division CalculatorDivide polynomials with exact fractions, aligned long division, and expanded synthetic division. Check each quotient and remainder.
Apply a science or ramp model
Punnett Square Calculator combines parental genotypes under the selected inheritance model. Its probabilities do not predict an individual child's outcome. Net Ionic Equation Calculator uses formulas and physical states to remove spectator ions. Read the solubility and net ionic equation guide before splitting weak electrolytes.
ADA Wheelchair Ramp Slope Calculator calculates runs and landings from rise, slope, and layout. Horizontal run differs from sloped surface length. Read the ADA ramp rules guide before treating a slope calculation as a complete accessible design.
- Punnett Square CalculatorCalculate exact genotype and phenotype ratios for up to four genes, ABO/Rh blood types, and recessive X-linked classroom crosses.
- Net Ionic Equation CalculatorPredict double-replacement products from two reactants. Balance molecular and ionic equations, cancel spectators, and explain solubility rules.
- ADA Wheelchair Ramp Slope CalculatorPlan equal ramp runs, landings, and straight or turning footprints. Check slope, rise, width, handrails, and available length.
