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 .
The two sample t test calculator provides the p-value, effect size, test power, outliers, distribution chart, and a histogram.
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.
Two sample and one sample t-test calculator with step by step explanation.
The calculator to perform t-Test for the Significance of the Difference between the Means of Two Independent Samples
