Calculators

Calculates the range (+/-) around a sample statistic (like mean or proportion) that likely contains the true population parameter.

This calculator determines the F-statistic, a value used in ANOVA (Analysis of Variance) to compare the variances of two or more samples. It helps determine if the variances are significantly different.

Calculates the relative risk (RR) to determine the likelihood of an event occurring in an exposed group versus a non-exposed group.

Calculates the long-term average outcome (mean) of a random variable.

This calculator applies the continuity correction, an adjustment used when approximating a discrete probability distribution (like the binomial distribution) with a continuous probability distribution (like the normal distribution).

Calculates probabilities for a continuous uniform distribution where all outcomes within a range are equally likely.

Evaluates the performance of a classification model using metrics derived from a confusion matrix, including accuracy, precision, recall, and specificity.

Calculates probabilities for the number of events occurring in a fixed interval of time or space.

This calculator determines the percentile rank of a given score within a dataset. It calculates the percentage of values in the dataset that fall below the specified score.

Calculates the sample proportion (p̂), which is an estimate of the population proportion. This calculator helps determine the proportion of a sample that possesses a specific characteristic.
