What is a p-value and what is a relation with hypothesis?

1 Answer


  • When you perform a hypothesis test in statistics, a p-value can help you determine the strength of your results.
  • p-value is a number between 0 and 1. Based on the value it will denote the strength of the results.
  • The claim which is on trial is called the Null Hypothesis.
  • Low p-value (≤ 0.05) indicates strength against the null hypothesis which means we can reject the null Hypothesis.
  • High p-value (≥ 0.05) indicates strength for the null hypothesis which means we can accept the null Hypothesis p-value of 0.05 indicates the Hypothesis could go either way.
  • To put it in another way, High P values: your data are likely with a true null.
  • Low P values: your data are unlikely with a true null.
