Calculators

Organizes data into classes and shows the frequency (count) of observations in each class.

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

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 covariance between two sets of data. Covariance measures the joint variability of two random variables, indicating how much they change together.

Calculates probabilities and percentiles associated with the standard normal (Z) distribution or any normal distribution.

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

Calculates the proportion of times an event occurs within a dataset (Frequency / Total).

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

Calculates the five-number summary (Minimum, First Quartile, Median, Third Quartile, Maximum) from a set of data, which is used to create a box plot.

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.
