What if the population standard deviations are known? The main purpose of this calculator is for comparing two population mean when sigma is unknown for both populations. In case that the population standard deviations are known, then you should use instead thisz-test for two means....
This simple t-test calculator, provides full details of the t-test calculation, including sample mean, sum of squares and standard deviation.T-Test Calculator Further InformationA t-test is used when you're looking at a numerical variable - for example, height - and then comparing the average...
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...
T-Test Calculator Compare the means of two samples using a single-sample or two-sample t-test below. Results: Two-tailed P: Left-tailed P: Right-tailed P: Test Statistic (t): Degrees of Freedom (df): Learn how we calculated thisbelow...
Two sample t-test is used to check whether the means of two groups are significantly different from each other. For example, if you want to see if mean weight of males and females have statistically significant difference between them. Independent T-test assumes that the two samples have ...
This calculator uses a two-samplettest, which compares two datasets to see if their means are statistically different. That is different from aone samplettest, which compares the mean of your sample to some proposed theoretical value. The most general formula for attest is composed of two means...

When entering raw data, the t test calculator will run the Shapiro-Wilk normality test and calculate outliers, as part of the test calculation, and will generate the R code for your data. Calculate testClearLoad last run Information Target ...
We use an independent two-sample t-test for comparison of two different samples’ means. For example, we can use the test comparing the average height of female college students with the average height of male college students. The number of college students of each gender should be the same...
