Statistics & graphs Calculators
Process replicate data, quantify spread, test hypotheses and analyse relationships with r, R² and regression.
Mean, median, mode & range
Summarize biological replicate data with n, mean, median, mode, minimum, maximum and range.
Open calculatorSD & standard error
Calculate sample and population standard deviation plus standard error of the mean for replicate measurements.
Open calculatorError bar ranges
Convert a mean and SD, SE or other symmetric error into lower and upper error-bar limits.
Open calculatorRegression, r & R²
Fit a straight line to paired biological data and calculate slope, intercept, Pearson r and R² with a graph.
Open calculatorTwo-sample t-test
Compare two biological samples with an independent Welch t-test or paired t-test and report t, df and two-tailed p.
Open calculatorChi-squared test
Calculate χ², degrees of freedom and an approximate p-value for goodness-of-fit data or a 2×2 association table.
