WebJan 7, 2024 · If the p value is lower than the significance level, the results are interpreted as refuting the null hypothesis and reported as statistically significant. Usually, the significance level is set to 0.05 or 5%. That means your results must have a 5% or lower chance of occurring under the null hypothesis to be considered statistically significant. WebMay 12, 2024 · To do this, we simply split it in half so that an equal proportion of the area under the curve falls in each tail’s rejection region. For α = .05, this means 2.5% of the area is in each tail, which, based on the z-table, corresponds to critical values of z ∗ = ±1.96. This is shown in Figure 7.5. 2.

WebApr 8, 2024 · p-values are the probability of procuring an effect no less than as intense as the one in the test data, assuming the null hypothesis to be true. For example, the significant value at 7% signifies that the p-values are less than 0.07 or p < 0.07. Correspondingly, when a result is significant at 2%, it means that p < 0.01. the invisible man full text
