WebP-value. P-value or calculated probability is the value of probability of an event occurrence if a null hypothesis turns out to be true. It can also be interpreted the other way round, in the sense that p-value helps to determine if a null hypothesis is true or not. It is used to quantify the idea of the statistical significance of evidence. WebJul 8, 2024 · The " r value" is a common way to indicate a correlation value. More specifically, it refers to the (sample) Pearson correlation, or Pearson's r.
