If the p-value is less than 0.05, we reject the null hypothesis that there is no difference between the means and conclude that there is a significant difference. If the p-value is greater than 0.05, we cannot conclude a significant difference. …Significant below 0.05. Greater than 0.05, not significant.
Is a low P value good?
The smaller the p-value, the stronger the evidence that you should reject the null hypothesis. A p-value less than 0.05 (usually ≤ 0.05) is statistically significant. This indicates strong evidence against the null hypothesis, since the probability that the null is correct is less than 5% (and the results are random).
What does a low P value mean?
A low p-value indicates the results are reproducible. A low p-value indicates that the effect is large or that the result is of great theoretical, clinical, or practical importance. A nonsignificant result that causes us not to reject the null hypothesis is evidence that the null hypothesis is true.
Is the P-value 0.1 significant?
significance levels. The significance level for a given hypothesis test is a value for which a P-value less than or equal to is considered statistically significant. Typical values for are 0.1, 0.05 and 0.01.
What does a p-value less than 0.05 mean?
P > 0.05 is the probability that the null hypothesis is true. 1 minus the P value is the probability that the alternative hypothesis is true. A statistically significant test result (P ≤ 0.05) means that the test hypothesis is incorrect or should be rejected.
Is the P-value 0.09 significant?
However, one cannot help but notice that a p-value of 0.09 is not a statistically significant result. … insignificant. temporarily irrelevant. just about to be insignificant.
What does the P value tell you?
The p-value, or probability value, gives you the probability that your data occurred under the null hypothesis. …p-value is a proportion: If your p-value is 0.05, it means that 5% of the time you would see a test statistic at least as extreme as what you found if the null hypothesis would be true.
What does a P-value of 0.2 mean?
If the p-value = 0.2, there is a 20% chance that the null hypothesis is correct. The P-value = 0.02 means that the probability of a type I error is 2%.
What does the P value of 0.000 mean?
The level of statistical significance is expressed by a p-value between 0 and 1. Some statistical software like SPSS sometimes gives a p-value. 000, which is impossible and should be taken as p. 001, i.e. the null hypothesis is rejected (the test is statistically significant). … P-value 0.000 means that the null hypothesis is true.
What does a P-value of 0.01 mean?
P0.01 ** P0.001. Most authors designate statistically significant as P 0.05 and statistically highly significant as P 0.001 (less than one in a thousand chances of being wrong).
What does Pvalue tell you?
The p-value, or probability value, gives you the probability that your data occurred under the null hypothesis. …p-value is a proportion: If your p-value is 0.05, it means that 5% of the time you would see a test statistic at least as extreme as what you found if the null hypothesis would be true. 16
