No. p-values are probabilities but they are not the only ones.

What compares the probability of an event occurring to the probability that it will not occur?

If the probability of an event occurring is p, then 1-p represents the probability of the same event not occurring. The value of p must lie between 0 and 1.


What does p value 1 means?

If p refers to the probability of an event, then the answer is "certainty".If p refers to the probability of an event, then the answer is "certainty".If p refers to the probability of an event, then the answer is "certainty".If p refers to the probability of an event, then the answer is "certainty".


What is the probability of not a?

The probability of not a is the same as the complement of a, which is found by subtracting the probability of a from one (i.e., P(not A)=1-P(A)).


What is a Bernoulli distribution?

A Bernoulli distribution is a discrete probability distribution which takes value 1 with success probability p and value 0 with failure probability q = 1 - p.


What is 1 minus the p-value?

It is the probability of the observed value.


If a p-value has a negative number will it be larger than 0.05?

If a p-value is negative then there is something very seriously wrong - either with the probability model or your calculations.If a p-value is negative then there is something very seriously wrong - either with the probability model or your calculations.If a p-value is negative then there is something very seriously wrong - either with the probability model or your calculations.If a p-value is negative then there is something very seriously wrong - either with the probability model or your calculations.


What is p value in regression analysis?

The p value is NOT a probability but a likelihood. It tells you the likelihood that the coefficient of a variable in regression is non zero. The p-value is: The probability of observing the calculated value of the test statistic if the null hypothesis is true


How do you compute the p-value?

The first step in calculating a p-value is to make a hypothesis of the statistical model for your study. You then assume that the hypothesis is true and calculate the probability of observing an outcome at least as extreme as the one that you did observe. This probability is the p-value.


Which expression is used to find the expected value of X in binomial distribution?

If X takes the value 1 with probability p and 0 with probability (1-p), and there are n independent trials then E(X) = np


In scientific terms what does P value stand for?

P-value is short for "Probability Value." It is a measure of statistical significance whereas the p-value is the probability of obtaining a test statistic at least as extreme as the one that was actually observed, assuming that the null hypothesis is true. The lower the p-value, the less likely the result is if the null hypothesis is true, and consequently the more "significant" the result is.


For some positive value of Z the probability that a standard normal variable is between 0 and z is 0.3770. The value of Z is?

P(0 < Z < z) = 0.3770 is the same as looking at P(Z < z) = 0.8770 because the other half of the curve (anything less than 0) has probability of 0.5. Now this is a problem of just looking it up from the table. The table gives a value z = 1.16 for the probability of 0.8770. So P(0 < Z < 1.16) = 0.3770.


Is Inferential statistics based on probability theory?

Yes; the p value used in hypothesis testing is probability. See the related link.
