  • Can the p value be the probability that the result is true?

  • In other words, the P value is computed based on the assumption that the difference was due to sampling error. Therefore the P value cannot tell you the probability that the result is due to sampling error. Nope. The P value is computed assuming that the null hypothesis is true, so cannot be the probability that it is true.

  • What is the p-value of a test?

  • The p -value is a number, calculated from a statistical test, that describes how likely you are to have found a particular set of observations if the null hypothesis were true. P -values are used in hypothesis testing to help decide whether to reject the null hypothesis. The smaller the p -value, the more likely you are to reject …

  • What does the p-value summarize?

  • Gravity Created by cboles10 Terms in this set (7) What does the p-value summarize? The p-value summarizes the evidence provided by the sample against the null hypothesis. What is a p-value? A p-value is the probability of seeing a simple statistic value as extreme or more extreme than the one observed in the sample, if the null hypothesis is true.

  • What does a p-value of 0 mean in statistics?

  • The p -value is conditional upon the null hypothesis being true is unrelated to the truth or falsity of the research hypothesis. A p -value higher than 0.05 ( 0.05) is not statistically significant and indicates weak evidence against the null hypothesis.
