T statistic negative
Web2. Calculate the t-statistic from the coefficient value. The next step is to convert the Pearson correlation coefficient value to a t-statistic. To do this, two components are required: r and the number of pairs in the test (n). In order to determine the number of pairs, simply count them manually or use the count function (=COUNT). http://www.csic.cornell.edu/Elrod/t-test/reporting-t-test.html
