# P-Value

Many students are unsure about the interpretation of $P$-values and other concepts related to tests of significance. These ideas are used repeatedly in various applications so it is important that they be understood.

For testing a statistical hypothesis we can use one of the methods like Rejection region method or $P$-value testing method. $P$-value is the probability that our null hypothesis is actually correct.The probability that the value of test statistic is at least as extreme as its computed value on the basis of the sample data under $H_{0}$ is known as the $P$-value.
