What is a p-value and why do we always see p ≤ 0.05 in our statistics class? In this video, I will explain the p-value in simple terms using an easy example with moldy apples at the grocery store. We’ll break down the null hypothesis, the alternative hypothesis, and what it really means when the p-value is less than 0.05.

The p-value is a key idea in hypothesis testing, used in statistics, data science, and research. It helps us measure how likely our experiment’s results could have happened if the null hypothesis were true. You’ll learn why 0.05 became the most common threshold, and why the p-value is sometimes misunderstood.

If you’ve ever been confused in class when your professor wrote p ≤ 0.05 on the board without explaining, this video is for you. By the end, you’ll understand what the p-value really tells us, how to interpret it, and why it matters in statistics.
