Type II Error

The error that occurs when a false null hypothesis is not rejected, also known as a false negative.

P Value

In hypothesis testing, the probability that the observed data (or a more extreme) would occur if the null hypothesis were true.

Hypothesized Reason

A proposed explanation based on limited evidence as a starting point for further investigation or experiment.
