The theory behind “p-values” and the null hypothesis might seem complicated initially, but understanding the concepts helps you navigate the world of statistics. Unfortunately, these terms often get misused in popular science, so it would be essential for everyone to understand the basics.
Calculating the “p-value” of a model and proving/disproving the null hypothesis is surprisingly simple with MS Excel. There are two ways to do it. Let’s dig in.
Null Hypothesis and p-ValueThe null hypothesis is a statement, also referred to as a default position, claiming that the relationship between the observed phenomena is non-existent. The null hypothesis can also apply to associations between two experimental groups. During the research, you test this hypothesis and try to disprove it.
For example, say you want to observe whether a particular fad diet has significant results. The null hypothesis, in this case, is that there is no significant difference in the test sub...
