Thepaired t-test calculatoralso called thedependent t-test calculatorcompares the means of the same items in two different conditions or any others connection between the two samples when there is a one to one connection between the samples - each value in one group is connected to one value ...
paired t-test: used to compare the mean of two different samples after an intervention or change How to Calculate T Using a One-Sample T-Test A one-sample t-test, or single-sample test, is used to compare a samplemeanto a population mean when the null hypothesis is that the sample me...
The calculator below implementspaired sample t-test(also known as adependent samples t-testor at-test for correlated samples). The t-test is also known as Student's t-test, after the pen name of William Sealy Gosset. Paired samples t-tests typically consist of a sample of matched pairs o...
1. 单样本t检验（One-sample t-test）：用于比较单个样本的均值与已知的总体均值之间是否存在显著差异。2. 独立样本t检验（Independent samples t-test）：用于比较两个独立样本的均值是否存在显著差异。3. 配对样本t检验（Paired samples t-test）：用于比较同一样本在两个不同条件下的均值差异。三、应用场景 T...
Attest compares the means of two groups. There are several types of two samplettests and this calculator focuses on the three most common: unpaired, welch's, and pairedttests. Directions for using the calculator are listed below, along with more information about two samplettests and help on...
t-test is used to determine, for example, if the means of two data sets differ significantly from each other. Our T test calculator is the most sophisticated and comprehensive T-test calculator online. Our Student's t-test calculator can do one sample t tests, two sample paired t-...
Thet-test for dependent means (also called a repeated-measurest-test, paired samplest-test, matched pairst-test and matched samplest-test) is used to compare the means of two sets of scores that are directly related to each other. So, for example, it could be used to test whether subj...

The t-Test is used in comparing the means of two populations. There are two approaches: When the samples from the two populations are independent; When the samples from the two populations are depended, i.e. when they are paired.
