HYPOTHESIS TEST(or test of significance)
|
is a procedure for testing a claim about a property of a population.
|
|
CRITICAL REGION(or rejection region)
|
is the set of all values of the test statistic that cause us to reject the null hypothesis.
|
|
SIGNIFICANCE LEVEL
|
is the probability that the test statistic will fall in the critical region when the null hypothesis is actually true.
|
|
CRITICAL VALUE
|
is any value that separates the critical region from the values of the tst statistic that do not lead to rejection of the null hypothesis
|
|
P-VALUE
|
is the probability of getting a value of the test statistic that is at least as extreme as the one representing the sample data, assuming that the null hypothesis is true.
|
|
POWER
|
a hypothesis test is the probability(1-beta)of rejecting a false null hypothesis
|
|
ALPHA
|
probability of a type I error ( rejection of a null hypothesis when it is true)
|
|
BETA
|
probability of a type II error (failing to reject a null hypothesis when it is true)
