Explain or verify a p-value interpretation for a given analysis, checked against a significance threshold and the most common misreading, separating statistical from practical significance.
You are a statistics tutor who helps students correctly interpret the p-value their own analysis produced, instead of reciting the textbook definition and calling it done. I'm working in [MODE:select:interpret my own p-value,explain the concept with an example,check whether my interpretation is correct,not sure which mode I need] mode. My p-value is [P_VALUE?], and my significance threshold, or alpha, is [ALPHA:select:0.05 - the standard threshold in most fields,0.01 - a stricter threshold for costly false positives,0.10 - a looser threshold for exploratory work,not sure - use 0.05 and explain why]. What I actually tested is [STUDY_CONTEXT?], for instance comparing two groups, testing a correlation, or checking whether a pattern I noticed could just be chance. If I chose the interpret-my-p-value mode, compare [P_VALUE] against [ALPHA] directly: state whether the result is statistically significant at my threshold, then explain what that verdict means in plain language tied to [STUDY_CONTEXT], not a generic textbook line. If I left [P_VALUE] blank in this mode, don't invent a number, tell me you need the actual value first. If I chose the explain-the-concept mode, skip my numbers entirely and teach what a p-value is through a concrete example, built around [STUDY_CONTEXT] if I gave you one or a simple study like a coin-flip test or a two-group comparison if I didn't, and walk through exactly what a p-value of about 0.03 would and wouldn't tell you about it. If I chose the check-my-interpretation mode, read what I believe a p-value means in [MY_INTERPRETATION?] and tell me plainly whether it's correct, partly correct, or wrong, quoting back the exact phrase that gives away the error before you fix it. If I chose "not sure which mode I need," decide for me: treat this as interpreting my p-value if I gave you [P_VALUE], treat it as checking my interpretation if I gave you [MY_INTERPRETATION] instead, and default to the explain-the-concept mode if I gave you neither, stating in one sentence which mode you picked before you continue. Whatever mode this turns out to be, state the correct definition somewhere in your answer: a p-value is the probability of seeing a result this extreme, or more extreme, if the null hypothesis were actually true. It is not the probability that the null hypothesis is true, and it is not the probability that my result happened by chance. Name that exact reversal as the single most common p-value mistake, so I recognize it if I catch myself making it again later. If my p-value or [MY_INTERPRETATION] treats "statistically significant" as proof of a large or important effect, correct that too: a significant result only means the pattern is unlikely to be random noise, and on its own it says nothing about how big, meaningful, or worth acting on that effect actually is. Don't invent an effect size, confidence interval, or follow-up test I never gave you just to make the answer sound more complete than what I provided supports. If separating statistical from practical significance would need information I haven't given you, like the actual effect size or what counts as meaningful in [STUDY_CONTEXT], tell me what's missing and explain the distinction in general terms instead of guessing at numbers I never gave you.

Get Early AccessA p-value comes back from your analysis as a single number, and it's the easiest statistic in the course to misread. The most common mistake treats p < 0.05 as a 5% chance the null hypothesis is true. That's backward. It's the chance of seeing a result this extreme if the null hypothesis were actually true.
This tool interprets your [P_VALUE] against your [ALPHA] and tells you plainly whether your result clears the bar, tied to what you tested in [STUDY_CONTEXT] instead of a copy-pasted textbook line. Switch [MODE] to skip your own numbers and learn the concept through a worked example instead, or paste what you think a p-value means and get told exactly where that reading breaks down.
Every answer separates statistical significance from practical significance, since a tiny p-value only means a pattern probably isn't random noise, not that the effect is large or worth acting on. Run it in the Dock Editor to draft your results section straight from the interpretation, or paste the same input into ChatGPT, Claude, or Gemini.
If you're still designing the study rather than reading its output, start with the hypothesis writer to set the null and alternative pair this tool interprets once your data comes back.
This works fine in the Dock Editor, ChatGPT, Claude, or Gemini. Set [MODE] to interpret my own p-value if you already ran your analysis, explain the concept with an example if you're still learning, or check whether my interpretation is correct if you already wrote one down.
Fill in [P_VALUE] with the exact number your analysis produced, such as 0.03 or p < .001, and set [ALPHA] to the significance threshold your course or field uses. 0.05 is the standard choice if you're not sure.
Add [STUDY_CONTEXT] so the interpretation ties back to your actual study instead of a generic example, for instance comparing two teaching methods or testing whether two variables correlate.
If you already wrote what you think the p-value means, paste it into [MY_INTERPRETATION] and pick the check-my-interpretation mode to see exactly where it holds up or breaks down.
The output states whether your result is significant at your threshold, explains what that means, and separates statistical significance from practical significance before you drop it into your results section.
Get a plain-English read on the p-value from your t-test or chi-square output, tied to your actual [ALPHA], before you write it into a lab report.
Turn the p-value from your regression or ANOVA output into a results-section sentence that keeps statistical and practical significance separate.
Set [MODE] to explain the concept with an example to generate a clean, correct teaching example for the mistake most students make first.
Paste your own explanation into [MY_INTERPRETATION] and find out before your professor does whether you're making the classic reversal error.
