Kahlil Sample

Posted on July 21, 2017

Chapter 13 The reasoning for saying “provided strong evidence that using the busy road was quickest” as opposed to “proved that using the busy road was quickest” is because the outcome of the experiment cannot be “proved” without measureable data. A very small p-value was... [Read More]
