This test evaluates the significance between two means when the sample size of each analysis is less than 30. Once the T value is obtained, you need to look it up on a probability table where the number of degrees of freedom is usually one less than the total number of observations between the two samples. Remember, the T test is determining of differences between the two means can be explained on the basis of chance alone. The higher the probability, the greater the chance that causes other than random sampling errors are affecting the values of the two means.
