An Explanation of P-Values and Statistical Significance
WebApr 9, 2024 · A p-value is the probability of observing a sample statistic that is at least as extreme as your sample statistic, given that the null hypothesis is true. For example, suppose a factory claims that they produce tires that have a mean weight of 200 pounds. An auditor hypothesizes that the true mean weight of tires produced at this factory is ... WebA p-value (probability value) is a value used in statistical hypothesis testing that is intended to determine whether the obtained results are significant. In statistical hypothesis testing, the null hypothesis is a type of hypothesis that states a default position, such as there is no association among groups or relationship between two ... hatcher hughes

WebJul 8, 2024 · P-value is the probability of getting our observed value or values that have same or less chance to be observed. Assume the average of sample means from the new design is 12.5. Since its a continuous function, the probability of a range is the area under the function curve. Thus, the p value for 12.5 is the green area in the graph above. booth bar
