High p value example
WebExamples Using P-value Formula Example 1: A statistician is testing the hypothesis H0: μ = 120 using the approach of alternative hypothesis Hα: μ > 120 and assuming that α = 0.05. The sample values that he took are as n =40, σ = 32.17 and x̄ = 105.37. What is the conclusion for this hypothesis? Solution: We know that, σ¯x = σ √n σ x ¯ = σ n WebFor example, a P value close to 0.05 often has an error rate of 25-50%. However, a P value of 0.0027 often has an error rate around 4.5%. That error rate is close to the rate that is often erroneously ascribed to a P value of 0.05. Tiny P values are great!

WebFeb 20, 2024 · The p-value or probability value is a number, calculated from a statistical test, that describes how likely your results would have occurred if the null hypothesis were true. A P-value less than 0.5 is statistically significant, while a value higher than 0.5 indicates the null hypothesis is true; hence it is not statistically significant.

WebFor example, a p value of 0.0254 is 2.54%. This means there is a 2.54% chance your results could be random (i.e. happened by chance). That’s pretty tiny. On the other hand, a large p-value of .9 (90%) means your results have a 90% probability of being completely random and not due to anything in your experiment.
