# How To Find The P Value Given T?

## How is the P value calculated?

To find the p-value for your test statistic: Look up your test statistic on the appropriate distribution — in this case, on the standard normal (Z-) distribution (see the following Z-table).

Find the probability that Z is beyond (more extreme than) your test statistic: The result is your p-value.

## How do you find the p value from T in R?

How to calculate a p-value from a t distribution in r –

## What is p value in t test?

p-value. In statistical hypothesis testing, the p-value or probability value is the probability of obtaining test results at least as extreme as the results actually observed during the test, assuming that the null hypothesis is correct.

## How do you find P value on calculator?

The p-value would be P(z <-2.01) or the area under the standard normal curve to the left of z = -2.01. Notice that the p-value is . 0222. We can find this value using the Normalcdf feature of the calculator found by pressing [2nd] [VARS] as noted above.
