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...

The one sample t-test calculator calculates the one sample t-test p-value and the effect size. When you enter the raw data, the one sample t-test calculator provides also the Shapiro-Wilk normality test result and the outliers.One sample t-test Hypotheses H0:μ = μ0 H1:μ ≠ μ0 On...
Notice that this is a one sample t test calculator. If instead you need to compare two means, you should use at-test for independent samples, instead. In a similar way, you may have two samples but they are paired, matched or repeated, which case the appropriate tool to use is thispai...
We have an excellent t-test calculator to help you with your calculations. You do not have to remember complex formulae or calculate the results by hand. Our t-test calculator helps you save time and provides a clear data interpretation. When you click on our home page, you will find an...
Step 3:Based on the significance level you chose and the type of tail, you find the critical t-statistics by either looking at a t-distribution table or use a calculator or Excel. Then, you clearly state your rejection region Step 4:You compute the t-statistic using the formula specified...
To calculate the t-value for an equal variance test, you can use the following formula: t=mean1-mean2n1-1)×var12+(n2-1)×var22n1+n2-21n1+1n2 Wherein, mean1 and mean2 represent the average values of the sample sets; var1 and var2 are the variances of the sample sets; and ...
This simple confidence interval calculator uses a t statistic and two sample means (M1 and M2) to generate an interval estimate of the difference between two population means (μ1 and μ2).The formula for estimation is:μ1 - μ2 = (M1 - M2)± ts(M1 - M2)where:...
