WebIn null-hypothesis significance testing, the p-value is the probability of obtaining test results at least as extreme as the result actually observed, under the assumption that the null hypothesis is correct. A very small p-value means that such an extreme observed outcome would be very unlikely under the null hypothesis.

If the overall ANOVA has a P value greater than 0.05, then the Scheffe’s test won’t find any significant post tests.

On the other hand, if your p-value is higher than 0.05, you can state that your data is not statistically different from a normal distribution. Web7 dec. 2024 · A p-value less than 0.05 (typically ≤ 0.05) is statistically significant.

Therefore, we reject the null hypothesis, and accept the alternative hypothesis. Web26 dec. 2014 · The null hypothesis of the Jarque-Bera test is a joint hypothesis of the skewness being zero and the excess kurtosis being zero. With a p -value > 0.05, one would usually say that the data are consistent with having skewness and excess kurtosis zero. A high p -value is expected here because you use normally distributed random numbers. it executive summary example

In this problem, the p-value (p<0.0002) is less than alpha (0.01), so we Reject the H0. The area of the test statistic is much less than the area of alpha (α). We reject the null hypothesis. WebP-value ≤ α: The differences between some of the means are statistically significant If the p-value is less than or equal to the significance level, you reject the null hypothesis and conclude that not all population means are equal.
