What does p-value of 0.5 mean?

Mathematical probabilities like p-values range from 0 (no chance) to 1 (absolute certainty). So 0.5 means a 50 per cent chance and 0.05 means a 5 per cent chance. In most sciences, results yielding a p-value of . 05 are considered on the borderline of statistical significance.

Is 0.006 statistically significant?

The p value of 0.006 means that an ARR of 19.6% or more would occur in only 6 in 1000 trials if streptomycin was equally as effective as bed rest. Since the p value is less than 0.05, the results are statistically significant (ie, it is unlikely that streptomycin is ineffective in preventing death).

What does AP value greater 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 false or should be rejected. A P value greater than 0.05 means that no effect was observed.
