(noun) a liquid or semi-liquid edible dressing or condiment served as an accompaniment to or an ingredient in a meat, dessert, or other food: pizza sauce, steak sauce, cranberry sauce, chocolate sauce, etc., or (verb) to add said sauce to something.
All hypothesis tests ultimately use a p-value to weigh the strength of the evidence (what the data are telling you about the population). The p-value is a number between 0 and 1 and interpreted in the following way: A small p-value (typically â¤ 0.05) indicates strong evidence against the null hypothesis, so you reject the null hypothesis.
1 The P-value is the probability of observing a sample statistic as extreme as the test statistic. 2  Since the test statistic is a z-score, use the Normal Distribution Calculator to assess the probability associated with the z-score. ( 3 See sample problems at the end of this lesson for examples of how this is done.).
