Every Data Scientist must have come across a question, What is P-value and how do we use it in our statistical analysis? At-least one question of every data science interview is about P-value and its…...

p-value Basics with Python Code

Towards Data Science

What is p-value? It is the probability that you will obtain a test result given an actual distribution. Or in an A/B test setting, it is the probability that we measure something, like an average…

Mastering P-values in Machine Learning

A p-value is a statistical metric that helps statisticians decide whether they should accept or reject the null hypothesis. The p-value measures the probability there is no relationship between…

Demystifying the P-Value for Data Scientists

Level Up Coding

So what is the p-value? The p-value is a number, calculated from a statistical test, which measures the probability of obtaining a result at least as extreme as the one observed, assuming the null hyp...

You’re Probably Misusing the P-Value

Towards Data Science

The p value is an important concept in frequentist statistics, and it is usually taught in introductory statistics courses. Unfortunately, many of these courses either do a poor job of explaining…

Wait, so what’s a P-Value?

Towards Data Science

If someone asked you to explain what a probability value (p-value) is, how would you intuitively explain? In this article, I’ll poke at this question and build up your intuition on what a p-value…

What is “p-value” short for? No, seriously.

Towards Data Science

Technically, p-value stands for probability value, but since all of statistics is all about dealing with probabilistic decision-making, that’s probably the least useful name we could give it. Painful…...

p-value and it’s significance

The p value is used all over statistics. In scientific articles we often read about p values. Everyone knows that you use p values to determine statistical significance in a hypothesis test. Despite…

What Should Your Decision Be When Your p-value = 0.052?

Towards Data Science

In hypothesis testing, the “p-value < α” is almost universally used as a criterion for statistical significance and also as a decision rule, where α is the level of significance. For example, in…

The Problem with P-Values
