The p-value is
Webb11 apr. 2024 · The p-value is 0.002, which tells us that the intercept term is statistically different than zero. In practice, we don’t usually care about the p-value for the intercept term. Even if the p-value isn’t less than some significance level (e.g. 0.05), we would still keep the intercept term in the model.

Webb15 juli 2015 · $\begingroup$ @StudentT While the test is supposed to be used on data drawn from a normal distribution, that doesn't stop people applying it to observations that are discrete values, such as exam marks or sums of Likert-scale items or IQs, for example. The question was not about what is assumed when deriving the distribution of the …
Webb0. It is true that the acceptance range for the p-value of a hypothesis test is rather arbitrary, but nevertheless a lower p-value means that the test result can be accepted with more certainty, because the p-value essentially defines the confidence interval for the estimate, so a narrower confidence interval should be regarded more significant ... WebbA p-value is a probability, a number between 0 and 1, calculated after running a statistical test on data. A small p-value (< 0.05 in general) means that the observed results are so unusual assuming that they were due to chance only. It is a way of telling if the results obtained should be taken seriously or not, based on running the experiment ...
