The critical value of t is associated with n-2 d.f. and an alpha of 0.05. You can look up the critical value of t in the table in Brower et al. (1998) or you can use Excel to find it. The function "tinv" will return the critical t value for a particular alpha level and df.

The formula for the t statistic is given below, but you don’t need to know it. The computer will calculate it for you. Notice that a key variable is n, the size of the sample. The sample size is also a key element of the degrees of freedom for the measurement (pick the smaller n: df = n -1). T-test in Excel. To run a t-test in Excel you need ...

Paired t-tests in Excel and JMP. Excel. 1. State H0 and H1; choose α. 2. Enter X1 and X2 values side by side in adjacent columns. 3. Make a new column for D = (X1 – X2). 4. Calculate mean and sample standard deviation of D. 5. Compute t statistic t = (assuming H0: μD = 0) 6. Use Excel function T.DIST to find p = probability in tail area(s) of t distribution.

Otherwise we use the t test statistic and the sample standard deviation (s); the t statistic has degrees of freedom (df) = n – 1. Compute the value of the appropriate test statistic. Calculate the p-value of the test statistic. This is done using Excel or computer software. We will explain this step in more detail on Monday.
