The P-value provides a measure of this distance. The P-value (in this situation) is the probability to the right of our test statistic calculated using the null distribution. The further out the test statistic is in the tail, the smaller the P-value, and the stronger the evidence against the null hypothesis in …

sample t tests, we will round the t-test statistic to 4 decimal places and the P-value to 3 significant figures. You should report these t-test results as t 92 = -7.1215, P = .000000000116 (left-tailed). Note that I included the degrees of freedom as a subscript; this is necessary because there is a different t

If all you are interested in is the p-value, a quick way to calculate this is by entering the following syntax directly into a cell: =T.TEST(array1, array2,tails,type) Here, array1 refers to the first set of data (A1:A11 in the example at left), array2 is the second set of data (B1:B11), tails refers to whether you want to run a …

T. To combine R max and R min, a parameter p is used; the value of which depends on the details of the construction. R T is given by: R T = p R max + (1 - p) R min [2] In effect, the BS EN ISO 6946 method uses a value of p=0.5 in all cases. For built-up metal cladding with rail and bracket spacer systems, a …
