Statistics is the branch of mathematics involved in the collection, analysis and exposition of data. Given a set of data, Wolfram|Alpha is instantaneously able to compute all manner of descriptive and inferential statistical properties and to produce regression analyses and equation fitting. Wolfram|Alpha's broad computational knowledge of statistical methods allows you to analyze, interpret and visualize your data quickly and accurately.
Compute statistical measures that summarize the properties of a dataset.
Calculate basic descriptive statistics for a dataset:
Compute a statistical quantity:
Fit different parameterized models to data.
Fit a line to two-dimensional data:
Fit a polynomial to given data:
Fit an exponential model to given data:
Use statistics and hypothesis tests to infer information from a dataset.
Find the sample size needed to estimate a binomial parameter:
Compute a confidence interval for a population mean:
Apply a test for a population mean:
Compute the probability of a random variable returning a specified value or falling within a range of values or determine the expected value of a random variable.
