Webb, the p-value = 0.03, then the probability of randomly selecting a sample of 100 users who spend, on average, 25 minutes on the yellow-background website is only 3%! In other words, the likelihood of getting a sample mean of 25 given that all sample means should be near 20 is only 3%. So, in a world where the null hypothesis is true--a hypothetical world … WebbIn this article, we will concentrate on hypothesis testing using the p-value.

WebbNow, a p-value of 0.05 means there is a 5% chance of getting that result when the null hypothesis is true. Therefore, if you do these 100 comparisons, you would expect to find 5 genes significant just by random chance. As such, to avoid making these false-positives (Type 1 Errors) we 'correct' the p-value thereby making the test more conservative. WebbA p-value, or probability value, is a number describing how likely it is that your data would have occurred by random chance (i.e. that the null hypothesis is true). The level of …
