• Centered Moving Average

This online calculator calculates centered moving average, which is used instead of moving average then number of periods is even

• Count to Probability

This online calculator takes a list of events along with number of times the particular event occured and calculates the probability (and log probability) of each event by dividing event count to the total number of events.

• Covariance Calculator

This online calculator computes covariance between two discrete random variables

• Estimated Mean of a Population

This online calculator allows you to estimate mean of a population using given sample

• Events timeline

This online calculator analyzes and summarizes sequence of events on a timeline. It calculates days passed between events, as well as statistical data, e.g. a mean time between events, a variance and a deviation

• Lagged scatterplot

This online calculator builds scatterplot of the time series against itself offset in time

• Mann-Whitney Test

This online calculator performs the Mann–Whitney U test (also called the Mann–Whitney–Wilcoxon (MWW), Wilcoxon rank-sum test, or Wilcoxon–Mann–Whitney test).

• P-value

This online calculator calculates p-value for one sided and two sided tests given the z-score

• Paired Sample t-Test

This online calculator performs t-Test for the Significance of the Difference between the Means of Two Correlated Samples

• Probability Urn simulator

This calculator simulates urn or box with colored balls often used for probability problems and can calculate probabilities of different events.

• Text fitness

This online calculator computes text "fitness". That is, how similar the given text to other texts written in English language.

• Text fitness (version 2)

This online calculator calculates measure known as fitness score, of how given text is similar to a typical English text. It uses frequencies of unigrams, bigrams and trigrams to calculate fitness score. The reference frequencies are calculated from Leipzig Corpora Collection and can be downloaded from http://practicalcryptography.com/cryptanalysis/text-characterisation/quadgrams/. The less value you get, the better.

• Text fitness (version 3)

This online calculator calculates measure known as fitness score, of how given text is similar to a typical English text. It uses logarithms of probabilites with normalization to calculate fitness score. The reference frequencies are calculated from Leipzig Corpora Collection and can be downloaded from http://practicalcryptography.com/cryptanalysis/text-characterisation/quadgrams/. The less value you get, the better.

• Time Series Autocorrelation function (ACF)

This online calculator computes autocorrelation function for given time series and plots correlogram

• Time Series Decomposition

This online calculator decomposes time series by extracting seasonality and trend from data

• Two sample t-Test

The calculator to perform t-Test for the Significance of the Difference between the Means of Two Independent Samples

• Z-score / Standard score

This online calculator computes the standard score of a raw score from the given mean of the population and the standard deviation of the population.

• Z-score from P-value

This online calculator calculates z score from p value
