P-value

Summary

The p-value of a test is the probability, under the null hypothesis, to get a result at least as extreme as the observed result. A small p-value is evidence against the null hypothesis. The node p-value gives the precise definition.

What this node needs for W2
  • edge instance_of in: at least two examples (0 of 2)
  • edge not_instance_of in: at least one non-example (0 of 1)
  • edge specializes both: the more general notions and the special cases (0 of 1)

The writing levels say how complete the text of a node is. They do not measure its truth.
