The value of the p-value ranges from 0 to 1. Unfortunately, Excel has no built-in method to find out the p-value of a given data set.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.Oct 13, 2023 · A p-value, or probability value, is a number describing how likely it is that your data would have occurred by random chance (i.e., that the null hypothesis is true). The level of statistical significance is often expressed as a p-value between 0 and 1. It is the cutoff probability for p-value to establish statistical significance for a given hypothesis test. For an observed effect to be considered as statistically significant, the p-value of the test should be lower than the pre-decided alpha value. Typically for most statistical tests (but not always), alpha is set as 0.05.For example, when testing H o: p = 0.25 versus H a: p < 0.25, the p-value turns out to be 0.1056. This is because the test statistic was –1.25, and when you look this number up on the Z-table (in the appendix) you find a probability of 0.1056 of being less than this value.In today’s fast-paced world, having a large screen cell phone is essential for many individuals who rely on their devices for work, entertainment, and socializing.
