The likelihood that an event will occur. In statistics, the probability (or P‐value) shows the likelihood that a research result could have occurred by chance alone.
For example, a P‐value of 0.05 means there is a five in 100 chance that the effect observed in the trial could have been due to chance. Results with P‐values of 0.05 or less are usually considered to be a reliable indication of an effect in the wider population and are called statistically significant. HTAI
