Journal Editorial Report: The week's best and worst from Bill McGurn, Allysia Finley and Kim Strassel. I was an academic scientist at Penn State in February 2020, when I became the target of an online ...

The null hypothesis is an essential concept in statistical analysis and hypothesis testing, often denoted as H0. The null hypothesis states that there is no significant difference between the ...

About twenty-five years ago, the software industry admitted a fundamental truth: We couldn't plan development work upfront because we didn't know what we didn't know. This realization birthed the ...

ABSTRACT: We present here an alternative definition of the P-value for statistical hypothesis test of a real-valued parameter for a continuous random variable X. Our ...

The probability value is the probability of a type I error, that is, the probability that the null hypothesis is true. If we have two groups, for example, a control and an experimental group, and the ...

Most scientific studies that get published have “positive results,” meaning that the study proved its hypothesis. Say you hypothesize that a honeybee will favor one flower over another, and your ...
