Which statement is correct about a p-value? The smaller the p-value the stronger the evidence in favor of the alternative hypothesis. The smaller the p-value the stronger the evidence in favor the null hypothesis Whether a small p-value provides evidence in favor of the null hypothesis depends on whether the test is one-sided or two-sided.

Question 2 0.25 pts Which of these statements about p-values is correct? O Ap-value is the probability that the null hypothesis is true. O Ap-value is the probability of making a Type 1 error. Assuming that the null hypothesis is true, a p-value is the probability of obtaining a test statistic as or more extreme than what is observed. When the p-value is

P – VALUE, A TRUE TEST OF STATISTICAL SIGNIFICANCE? A CAUTIONARY NOTE - PMC
The use of confidence intervals in addressing hypothesis testing is one of the four popular methods journal editors and eminent statisticians have issued statements supporting its use 19. In line with this, the American Psychological Association’s Board of Scientific Affairs commissioned a white paper, “Task Force on Statistical Inference”. The Task Force suggested, “When reporting inferential statistics (e.g. t - tests, F - tests, and chi-square) include information about the obtained ….. value of the test statistic, the degree of freedom, the probability of obtaining a value as extreme as or more extreme than the one obtained [i.e., the P value]…. Be sure to include sufficient descriptive statistics [e.g.

p-value - Wikipedia
3 weeks ago - For example, AMA style uses "P value", APA style uses "p value", and the American Statistical Association uses "p-value". In all cases, the "p" stands for probability. ^ The statistical significance of a result does not imply that the result also has real-world relevance.

Understanding P-Values and Statistical Significance
August 11, 2025 - Use adjustments for multiple testing, such as the Bonferroni correction, to keep the overall error rate under control. Report all analyses conducted, not just the ones that turned out significant. The bottom line: statistical significance is most trustworthy when the analysis plan is transparent, limited to the main research questions, and adjusted for the number of tests performed. In statistical hypothesis testing, you reject the null hypothesis when the p-value is less than or equal to the significance level (α) you set before conducting your test.

r/AskStatistics on Reddit: What is p value?
August 20, 2024 -

I always get super confused about what the p value is and what it tells us about our hypothesis. Would love to understand how can one interpret it!

P value is the probably of seeing something at least as extreme as what you have seen (assuming the null hypothesis is true)

As an example, you have a coin. You assume the coin is fair (NULL HYPOTHESIS). Given the null hypothesis, you expect 50% tails and heads after many many runs of coin tosses. The coin gives you 90% heads (and 10% tails) after a thousand runs of coin tosses. Given you assume that the coin is fair, how much deviation do you accept from the 50/50 situation? Is it okay that 55% are one side for it to still be fair after 1000 tosses? 60%? 70%? P-value is basically the probability of seeing something so extremely deviatiang from the 50/50 that you would still accept the claim that the coins are fair. If you throw the coin 10 times, would you say the coin is fair if 90% of the tosses are heads? What if you throw 100 times and still 90% are heads? A 1000 times? In this example, p-value reflects the probability of witnessing the kind of deviation from 50% heads that you do witness. With 10 tosses it would be small, with a 1000 tosses it would be very very small, again, GIVEN YOU EXPECT 50/50. This is why sample size matters. The p-value tells you how unlikely the observed effect is given what you expect (a 50/50 amount of heads and tails in our case). After 1000 throws, if you assume the outcome should be 50% heads (and tails), receiving 90% heads would be VERY unlikely. P-value would then be the probability of seeing 90% heads given you expect to see 50% heads.
