What does it mean when the p-values are high and low?

Answer»

A p-value is the MEASURE of the probability of having results equal to or more than the results achieved under a specific hypothesis assuming that the null hypothesis is correct. This represents the probability that the observed difference occurred randomly by chance.

  • Low p-value which means values ≤ 0.05 means that the null hypothesis can be rejected and the DATA is unlikely with true null.
  • High p-value, i.e values ≥ 0.05 indicates the strength in favor of the null hypothesis. It means that the data is like with true null.
  • p-value = 0.05 means that the hypothesis can GO either WAY.
