The calculator returns the cumulative probability, so to find the p-value we can simply use 1 – 0.98303 = 0.01697. Since the p-value (0.01697) is less than our alpha level of 0.05, we reject the null hypothesis of our test. We have sufficient evidence to say that our results are statistically significant at alpha level 0.05.Analysts and investors use EPS to establish a company's financial strength.

Your p-value is displayed using scientific notation. You need to move the decimal point to the left 15 places, which produces a very, very small p-value. P Value Calculator. Use this calculator to compute a two-tailed P value from any Z score, T score, F statistic, correlation coefficient (R), or chi-square value. Once you have obtained one of these statistics (from a publication or even another program) the P value helps interpret its statistical significance. To compute a p-value by hand all you do is find the area “outside” of the test ratio value from step 6 in ‘normal curve’ – that is your p-value. There are two areas “outside” of your test ratio from step 6 – one on each side of the normal curve. The p-value is the area to the “outside” of the z-scores of -2.0 and 2.0.Monday night when Stewart savaged some of Donald Trump’s supporters.
