Use the Analysis Tool. Pak to perform complex data analysis. The Two Sample t Test analysis tools test for equality of the population means that underlie each sample. The three tools employ different assumptions that the population variances are equal, that the population variances are not equal, and that the two samples represent before treatment and after treatment observations on the same subjects.

For all three tools below, a t Statistic value, t, is computed and shown as t Stat in the output tables. Depending on the data, this value, t, can be negative or nonnegative. Under the assumption of equal underlying population means, if t lt 0, PT lt t one tail gives the probability that a value of the t Statistic would be observed that is more negative than t. If t 0, PT lt t one tail gives the probability that a value of the t Statistic would be observed that is more positive than t. Critical one tail gives the cutoff value, so that the probability of observing a value of the t Statistic greater than or equal to t Critical one tail is Alpha. PT lt t two tail gives the probability that a value of the t Statistic would be observed that is larger in absolute value than t. Microsoft Office Home And Student 2010 Tested Variable MeaningP Critical two tail gives the cutoff value, so that the probability of an observed t Statistic larger in absolute value than P Critical two tail is Alpha. Test Paired Two Sample For Means. You can use a paired test when there is a natural pairing of observations in the samples, such as when a sample group is tested twice before and after an experiment. This analysis tool and its formula perform a paired two sample Students t Test to determine whether observations that are taken before a treatment and observations taken after a treatment are likely to have come from distributions with equal population means. This t Test form does not assume that the variances of both populations are equal. Note Among the results that are generated by this tool is pooled variance, an accumulated measure of the spread of data about the mean, which is derived from the following formula. Test Two Sample Assuming Equal Variances. This analysis tool performs a two sample students t Test. This t Test form assumes that the two data sets came from distributions with the same variances. It is referred to as a homoscedastic t Test. You can use this t Test to determine whether the two samples are likely to have come from distributions with equal population means. Test Two Sample Assuming Unequal Variances. This analysis tool performs a two sample students t Test. This t Test form assumes that the two data sets came from distributions with unequal variances. It is referred to as a heteroscedastic t Test. As with the preceding Equal Variances case, you can use this t Test to determine whether the two samples are likely to have come from distributions with equal population means. Use this test when there are distinct subjects in the two samples. Use the Paired test, described in the follow example, when there is a single set of subjects and the two samples represent measurements for each subject before and after a treatment. The following formula is used to determine the statistic value t. The following formula is used to calculate the degrees of freedom, df. Because the result of the calculation is usually not an integer, the value of df is rounded to the nearest integer to obtain a critical value from the t table. The Excel worksheet function T. TEST uses the calculated df value without rounding, because it is possible to compute a value for T. TEST with a noninteger df. Because of these different approaches to determining the degrees of freedom, the results of T. TEST and this t Test tool will differ in the Unequal Variances case. Class. Zone.
