How to Interpret a P-Value Less Than 0.05 (With Examples)

WebIn most health-related studies a p-value < 0.05 (i.e. less than 5%) is considered low enough to conclude that the observed results are so unusual given that there is no effect. Why use a threshold of 0.05? The 0.05 is called the level of statistical significance. Keep in mind that there is nothing special about 0.05. WebA randomized trial comparing the efficacy of two drugs showed a difference between the two (with a P-value <.05). Assume that in reality, however, the two drugs do not differ.
