Your friend and you made toss coin in the air: If it is tails you lose 5 dollars and if it comes heads you gain 5 dollars. It does not mean the null hypothesis is certainly true but it also cannot be avoided. But if the p-value is greater or equal to the alpha you cannot reject the null hypothesis.You have got statistical proof that the alternative hypothesis is true.

It can be about research or a simple bet we made with our friend. We use the probability value where we try to test a hypothesis. Where Do We Use The P Value In Real Life? We can compare the mathematical results to these hypotheses and reconsider our path without spending a great amount of time in research. P-value allows us to test the hypothesis on our subject. Statistical calculations cannot give you an absolute truth but they will help you have a good idea of your researches. But even in such a case, you can’t be sure if something is happened because of coincidence or simply luck since it is impossible to observe everything. While doing research with large populations you have to calculate the statistics for each individual. In this article, you will learn how we use it, where do we use it and how can we calculate it in Excel in various ways. It is a very important and commonly used statistical term and can be easily calculated in data analysis programs like Microsoft Excel. An alternate hypothesis claims that the results we get are not luck but there are outside elements that affect our results.A null hypothesis is a hypothesis that claims the results we get are caused by pure luck.It simply tells us what are the odds of getting these results if our null hypothesis is true. P-value is a statistical term that helps you to determine, if the hypothesis you use is true, the probability of the sampling variation. Where Do We Use The P Value In Real Life?.
