P values can be "hacked" to give a significant result when one doesn't actually exist, leading to unreproducible research. Other times researchers approach hypothesis testing backwards, byletting the P value decide the hypothesisafter the fact. ...
You raise a good point about alpha. And the fact that you’re comparing alpha (which is an error rate) to the p-value (not an error rate) definitely adds to the confusion. I write about this and other reasons forwhy p-values are misinterpreted so frequently. (There’s some historical ...
The P value is defined as the probability, under the assumption of no effect or no difference (the null hypothesis), of obtaining a result equal to or more extreme than what was actually observed. Apvalue is calculated under the assumption that the medicationdoes not workand tells us the pr...

P value is one of the most important values in research, yet it is a challenging concept to understand. In this article, I am taking an intuitive approach using a weight loss example to explain the concept of p-value. Of course, I have omitted the details and technical terms to focus ...

On the other hand, when a p value in regression is greater than the significance level, it indicates there is insufficient evidence in your sample to conclude that a non-zero correlation exists. The regression output example below shows that the South and North predictor variables are statisticall...
“the probability of obtaining test results at least as extreme as the results actually observed, assuming that the null hypothesis is correct.” When we introduce p-values to non-statisticians in Microsoft’s internal A/B testing classes, we ...
While the P/E ratio is a commonly used metric, you can also use several other alternatives. One such alternative is the price-to-book (P/B) ratio. This ratio compares a company's market value to its book value. The book value represents the company's net asset value according to its...
