Calculators

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

Calculates Spearman's rank correlation coefficient, measuring the strength and direction of association between two ranked variables.

Identifies potential outliers in a dataset using the IQR * 1.5 rule (calculating fences).

Calculates the Interquartile Range (IQR), which is the difference between the third quartile (Q3) and the first quartile (Q1). The IQR measures the spread of the middle 50% of a dataset.

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

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 the mean and standard deviation of the sampling distribution for sample proportions (p̂).

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.

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