What is a test statistic? - Minitab Express
The observed value of z is the value calculated for a sample statistic such as . a. The rejection region lies to the left of z = –1.96 and to the right of z = 1.96.

Determine the P-value associated with the observed value of the test statistic. State the conclusion, which will be to reject H0 if P-value ( ( and not to reject H0 otherwise. The conclusion should then be stated in the context of the problem, and the level of significance should be included.

The p-value associated with the observed value of the test statistic is the probability of getting the observed value or a value more extreme (in the direction of Ha), assuming H0 is true. The p-value represents the probability of observing a sample outcome more contradictory to H0 than the observed …

P-value: For a test statistic , consider a family of critical regions each with different sizes. For the observed value of the test statistic from the sample, consider the subset of critical regions for which we would reject the null hypothesis, . The p-value is the maximum size of the tests in the subset , p-value = .

2. Calculate the value of the test statistic on which the test will be based. This statistic usually measures how far the data are from . 3. Find the P-value for the observed data. This is the probability, calculated assuming that is true, that the test statistic will weigh against at least as strongly as it does for these data. 4. State a ...

Statistic: Calculate the value of the statistic from the observed data. Simulation: Assume the null model is true, and simulate the random process under this model, producing data that “could have been” produced in the study if the null model were true. Calculate the value of the statistic from these “could have been” data.
