(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.
the p value is calculated for a particular sample mean here we assume that we obtained a sample mean x and want to find its p value it is the probability that we would obtain a given sample mean that is greater than the absolute value of its z score or less than the negative of the absolute value of its z scorehe easy way the methods above demonstrate how to calculate the p values directly making use of the standard formulae there is another more direct way to do this using the t test command the t test command takes a data set for an argument and the default operation is to perform a two sided hypothesis test
