WebApr 13, 2024 · A dataset for Bax, Bcl2 and Cc3 was obtained in the statistical software GraphPad Prism 9.3.0.463 (GraphPad Software©, San Diego, CA, United States). To find out, whether the data obtained is following a Gaussian distribution or not, histograms in GraphPad were obtained to decide further statistical testing. Fisher's method combines extreme value probabilities from each test, commonly known as "p-values", into one test statistic (X ) using the formula where pi is the p-value for the i hypothesis test. When the p-values tend to be small, the test statistic X will be large, which suggests that the null hypotheses are not true for every test. When all the null hypotheses are true, and the pi (or their corresponding test statistics) are inde…
