23 Απρ 2020 · A two sample t-test is used to test whether or not the means of two populations are equal. This type of test assumes that the two samples have equal variances. If this is not the case, you should instead use the Welch’s t-test calculator .
This calculator uses a two-sample t test, which compares two datasets to see if their means are statistically different. That is different from a one sample t test, which compares the mean of your sample to some proposed theoretical value.
Choose the two-sample t-test to check if the difference between the means of two populations is equal to some pre-determined value when the two samples have been chosen independently of each other. In particular, you can use this test to check whether the two groups are different from one another.
In this version of a t-test, we are testing the probability that two independent samples were drawn from the same population based on the means (and variances) of those samples. More specifically, this version of a t-test is used when: You have two independent samples.
