An interactive visualisation of the distribution of p-values when comparing two groups

A blog about the visualisation of Confidence intervals

Correlation is one of the most widely used tools in statistics. The correlation coefficient summarizes the association between two variables. In this visualization I show a scatter plot of two variables with a given correlation. The variables are â€¦

Introduction to simulation - first of a series of short lectures given at University of Oxford in February 2021. Very basic for those with little or no background, starting with simulation in Excel. In part 1, we simulate random data to show how easy â€¦

I just published a new interactive visualization in my series of basic statistical concepts and techniques. This time I am trying to show how the t-distribution and the normal distribution differs, and how they become very similar for larger sample â€¦

Much has been said about significance testing â€“ most of it negative. Methodologists constantly point out that researchers misinterpret p-values. Some say that it is at best a meaningless exercise and at worst an impediment to scientific discoveries. â€¦
