RMSE Calculator
Calculate root mean squared error from the sum of squared errors and observation count.
Calculate root mean squared error from the sum of squared errors and observation count.
Move between confidence intervals, sample size, standard error, relative variability, correlation, regression and prediction error.
Calculate a z-based confidence interval for a population mean from a sample mean, standard deviation and sample size.
Open calculatorEstimate the required sample size for a population proportion from a z critical value, expected proportion and margin of error.
Open calculatorCalculate the standard error of a sample mean from standard deviation and sample size.
Open calculatorCalculate the coefficient of variation as standard deviation relative to the absolute mean.
Open calculatorCalculate Pearson's correlation coefficient from summary statistics.
Open calculatorCalculate the slope and intercept of a simple linear regression from summary statistics.
Open calculatorCalculate root mean squared error from the sum of squared errors and observation count.
RMSE Calculator is an educational statistics and data-science tool for exploring a standard quantitative relationship.
Enter the requested values using the stated definitions. The calculator validates the numerical domain and applies RMSE = √(SSE / n).
Variables: SSE = Sum of squared errors (SSE); n = Number of observations.
Example: SSE = 25, n = 5 → RMSE = √5 ≈ 2.2361.
It is intended for study, classroom exercises and quick exploration of the stated statistical relationship.
No. Sampling design, assumptions, data quality, dependence, distribution shape, bias and model diagnostics may materially affect a real analysis.
