Highly significant p value

WebAn observed event is considered to be statistically significant when it is highly unlikely that the event happened by random chance. More specifically, an observed event is statistically significant when its p -value falls below a certain threshold, called the level of significance. WebTo determine whether a result is statistically significant, a researcher calculates a p-value, which is the probability of observing an effect of the same magnitude or more extreme given that the null hypothesis is true. …

WebOct 1, 2024 · Yes, you can have high p-values for individual coefficients with a good fit and low p-values with a poor fit. The reason for this is straightforward: goodness of fit is a different question than whether the slope of the X, Y relationship is 0 in the population.

WebMathematical probabilities like p-values range from 0 (no chance) to 1 (absolute certainty). So 0.5 means a 50 per cent chance and 0.05 means a 5 per cent chance.
