                                         Conclusion

               Statistical Conclusions:

               1.      If  the  observed  test  statistic  (      or        )  falls  in  the
                       “rejection  region,”  outside  of  the  critical  value(s),  the
                       conclusion is to Reject the Null Hypothesis.

                       a.     Here, we say the results are “statistically significant”
                              with a pre-specified level of confidence.

               2.      If the observed test statistic (      or       ) does not fall in the
                       “rejection  region,”  inside  of  the  critical  value(s),  the
                       conclusion  is  to  Fail  to  Reject  the  Null  Hypothesis.


               In other words, if test statistics value is greater than critical value,
               null hypothesis is rejected. If test statistics value is less than critical
               value, null hypothesis is fail to reject.

               Research Conclusions:

               The conclusion must also be stated in terms relating to the original
               research  question.  For  example,  if  null  hypothesis  is  “There  is  no
               significance  difference  in  self-efficacy  between  male  and  female
               teachers” and statistical conclusion is “reject null hypothesis” then
               the research conclusion would be “There is a significance difference
               in self-efficacy between male and female teachers”.
