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. WebMar 6, 2024 · A 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 statistical significance is often expressed as a p -value between 0 and 1. The smaller the p-value, the stronger the evidence that you should reject the null hypothesis.
WebJan 22, 2024 · P-value. P-value is used to find extreme values when the null hypothesis (h 0) is true. In simpler words, it is used to reject or support the null hypothesis during hypothesis testing. In data science, it gives valuable insights on the statistical significance of an independent variable in predicting the dependent variable.
