Statistical hypothesis testing provides objective criteria for deciding whether hypotheses are supported by data. Suppose we hypothesized that participation in a stress- management program would reduce anxiety levels among patients with cancer. The sample is 25 patients in the control room who do not participate in the program and 25 experimental patients who do. The mean post treatment anxiety score for experimentals is 15.8 and that for controls is 17.9.Group differences are in the predicted direction, but the results might reflect sampling fluctuations. With a new sample, group means might be nearly identical. Statistical hypothesis testing allows researchers to make objective decisions about whether study results likely reflect chance sample differences or true population differences.
Hypothesis testing is based on negative inference. In our example, patients participating in the intervention had lower mean anxiety scores than control group patients. There are two possible explanations :1) the intervention was successful in reducing anxiety or 2) the differences resulted from chance factors, such vss group differences in anxiety even before the treatment. The first explanation is research hypothesis and second is the null hypothesis. The null hypothesis, it maybe recalled, states that there is no relationship between variables. Statistical hypothesis testing is basically a process of rejection. It cannot be demonstrated directly that the research hypothesis is correct, but, using theoretical sampling distributions, it can be shown that the null hypothesis has a high probability of being incorrect.
