The p-value is a calculation that we make during hypothesis testing to determine if we reject the null hypothesis or fail to reject it.The p-value is calculated by first finding the z test statistic.

Don't Miss: Find the Formula in an Arithmetical Sequence. P-Value Formula & Arguments. As said, when testing a hypothesis in statistics, the p-value can help determine support for or against a claim by quantifying the evidence. The Excel formula we'll be using to calculate the p-value is: =tdist(x,degfreedom,tails). When you test a hypothesis about a population, you can use your test statistic to decide whether to reject the null hypothesis, H 0. You make this decision by coming up with a number, called a p-value. A p-value is a probability associated with your critical value. The critical value depends on the.
How To Calculate P Value In Excel
Once this is known we then need to find the probability of our population having a value more extreme than the test statistic. This is done by looking up the probability in a normal distribution table. We then interpret the results by comparing the p-value to the level of significance.
