This 'utility' program implements a standard independent means t-test on data where you only have access to the mean, sd, and n for each sample.

example 1: Twelve younger adults and twelve older adults conducted a life satisfaction test. The data are presented in the table below. Compute the appropriate t  T-test online. To compare the difference between two means, two averages, two proportions or two counted numbers.

25 Jan 2012 The t distribution (you may have heard it called Student's t) is a probability Statistical tables for the t distribution are readily available online and in textbooks. This is that magic number that your statistics software spits out; 

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   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   You are about to enter two sets of data so that Student's t-test can be used to determine if the averages of your two samples are significantly different. For each   This free online software (calculator) computes the one- and two-sided T-Tests about the difference of means. This R module is used in Workshop 6 of the 

T-test is small sample test. It was developed by William Gosset in 1908. He published this test under the pen name of "Student". Therefore, it is known as Student's t-test. For applying t-test, the value of t-statistic is computed. For this, the following formula is used You can run the Student t tests using typical statistical software and interpret the output produced. In this example, you’ll be using the software package OpenStat. The basic idea of a t test All the Student t tests for comparing sets of numbers are trying to answer the same question, “Is the observed difference larger […] The Student's t-test is used to determine if means of two data sets differ significantly. This calculator will generate a step by step explanation on how to apply t - test. To test this, researchers would use a Student’s t-test to find out if the results are repeatable for an entire population. The T Score. The t score is a ratio between the difference between two groups and the difference within the groups. The larger the t score, the more difference there is between groups. t test to compare two means. One sample t test. Compare observed and expected means. Post test following two-way (or higher) ANOVA. Confidence interval of a sum, difference, quotient or product of two means. Confidence interval of a standard deviation. Linear regression. 'Student's' t Test is one of the most commonly used techniques for testing a hypothesis on the basis of a difference between sample means. Explained in layman's terms, the t test determines a probability that two populations are the same with respect to the variable tested.
