When heating up, the balloon slowly rises and flies up in the air again. Explanation 1: The volume of the balloon decreases by the low temperature, because […]
What does it mean when correlation is significant at the 0.01 level?
What does it mean when correlation is significant at the 0.01 level? Saying that p<0.01 therefore means that the confidence is >99%, so the 99% interval will (just) not include the tested value. They do not (necessarily) mean it is highly important. The significance level, also denoted as alpha or α, is the probability of […]

Because of the inverse square nature of the gravity force, the force approaches zero for large distances, and it makes sense to choose the zero […]
