Webb8 feb. 2024 · Probability is the likelihood of an event or more than one event occurring. Probability represents the possibility of acquiring a certain outcome and can be calculated using a simple formula. Probability may also be described as the likelihood of an event occurring divided by the number of expected outcomes of the event. Webb17 apr. 2014 · In technical terms, a P value is the probability of obtaining an effect at least as extreme as the one in your sample data, assuming the truth of the null hypothesis. For example, suppose that a vaccine study produced a P value of 0.04.
