Calculators

Calculates a single value used to estimate a population parameter, such as the sample mean estimating the population mean.

Calculates the difference between the observed value and the predicted value from a regression model.

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

Helps organize numerical data to visualize its distribution shape while retaining individual data values.

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

Calculates the average cycle time, which is the time it takes to complete a process or task.

Calculates probabilities for the number of trials needed to get the first success in Bernoulli trials.

Performs an F-test to compare the variances of two populations.

Calculates the sum of squared deviations from the mean, a key component in variance and regression analysis.

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