Difference between Student's t-test and Variance

Student's t-test vs. Variance

The t-test is any statistical hypothesis test in which the test statistic follows a Student's ''t''-distribution under the null hypothesis. In probability theory and statistics, variance is the expectation of the squared deviation of a random variable from its mean.

Similarities between Student's t-test and Variance

Student's t-test and Variance have 18 things in common (in Unionpedia): Analysis of variance, Bias of an estimator, Central limit theorem, Chi-squared distribution, Expected value, F-test, Independence (probability theory), Linear regression, Normal distribution, Outlier, Pooled variance, Sample mean and covariance, Skewness, Standard deviation, Standard error, Statistical hypothesis testing, Statistical population, Statistics.

Analysis of variance

Analysis of variance (ANOVA) is a collection of statistical models and their associated estimation procedures (such as the "variation" among and between groups) used to analyze the differences among group means in a sample.

Bias of an estimator

In statistics, the bias (or bias function) of an estimator is the difference between this estimator's expected value and the true value of the parameter being estimated.

Central limit theorem

In probability theory, the central limit theorem (CLT) establishes that, in some situations, when independent random variables are added, their properly normalized sum tends toward a normal distribution (informally a "bell curve") even if the original variables themselves are not normally distributed.

Expected value

In probability theory, the expected value of a random variable, intuitively, is the long-run average value of repetitions of the experiment it represents.

F-test

An F-test is any statistical test in which the test statistic has an ''F''-distribution under the null hypothesis.

Independence (probability theory)

In probability theory, two events are independent, statistically independent, or stochastically independent if the occurrence of one does not affect the probability of occurrence of the other.

Linear regression

In statistics, linear regression is a linear approach to modelling the relationship between a scalar response (or dependent variable) and one or more explanatory variables (or independent variables).

Normal distribution

In probability theory, the normal (or Gaussian or Gauss or Laplace–Gauss) distribution is a very common continuous probability distribution.

Outlier

In statistics, an outlier is an observation point that is distant from other observations.

Pooled variance

In statistics, pooled variance (also known as combined, composite, or overall variance) is a method for estimating variance of several different populations when the mean of each population may be different, but one may assume that the variance of each population is the same.

Sample mean and covariance

The sample mean or empirical mean and the sample covariance are statistics computed from a collection (the sample) of data on one or more random variables.

Skewness

In probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean.

Standard deviation

In statistics, the standard deviation (SD, also represented by the Greek letter sigma σ or the Latin letter s) is a measure that is used to quantify the amount of variation or dispersion of a set of data values.

Standard error

The standard error (SE) of a statistic (usually an estimate of a parameter) is the standard deviation of its sampling distribution or an estimate of that standard deviation.

Statistical hypothesis testing

A statistical hypothesis, sometimes called confirmatory data analysis, is a hypothesis that is testable on the basis of observing a process that is modeled via a set of random variables.

Statistical population

In statistics, a population is a set of similar items or events which is of interest for some question or experiment.

Student's t-test and Variance Comparison

Student's t-test has 102 relations, while Variance has 125. As they have in common 18, the Jaccard index is 7.93% = 18 / (102 + 125).
