The paired t-test calculator calculates the paired t-test p-value. When you enter raw data, the paired t-test calculator also calculates the Shapiro-Wilk normality test and calculates the outliers. Enter raw data directly Enter raw data from excel ...

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...
Performs unpaired t test, Weldh's t test (doesn't assume equal variances) and paired t test. Calculates exact P value and 95% confidence interval. Clear results with links to extensive explanations.

Here you can not only easily perform one-sample t-tests, but also two-sample t-tests, as well as paired t-tests. Do you prefer to find the p-value from t-test, or would you rather find the t-test critical values? Well, this t-test calculator can do both! 😊 What does a t-...
Our Student's t-test calculator can do one sample t tests, two sample paired t-tests and two sample unpaired t-tests. Results page will give you t-Score, standard error of difference, degrees of freedom, two-tailed p-value, mean difference and confidence range. You can choose the confide...
Instructions:This calculator conducts a t-test for two paired samples. This test applies when you have two samples that are dependent (paired or matched). Please select the null and alternative hypotheses, type the sample data (or paste it from Excel) and the significance level, and the resul...
t.test(x1, x2 = NULL, alternative = "two.sided", paired = FALSE, mu = 190, conf.level = 0.95)For one sample x2 is NULL.mu - the expected difference, in this example mu=190. Two-sample t-test - equal variances (pooled-variance) (Go to the calculator) What is the two-sample...
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...
