A critical value is a point on the distribution of the test statistic under the null hypothesis that defines a set of values that call for rejecting the null hypothesis. This set is called critical or rejection region. Usually, one-sided tests have one critical value and two-sided test have two critical values.
The traditional hypothesis-driven scientific approach focuses on collecting new or reusing high quality data, primarily collected by the individual scientist, with selective use of ancillary data.
Examples on Critical Value Example 1: Find the critical value for a left tailed z test where \u03b1 = 0.012. Solution: First subtract \u03b1 from 0.5. Thus, 0.5 - 0.012 = 0.488.
Step 1: State your null and alternate hypothesis. ... Step 2: Collect data. ... Step 3: Perform a statistical test. ... Step 4: Decide whether to reject or fail to reject your null hypothesis. ... Step 5: Present your findings.
The most common null hypothesis test for this type of statistical relationship is the t test . In this section, we look at three types of t tests that are used for slightly different research designs: the one-sample t test, the dependent-samples t test, and the independent-samples t test.
