Inferential Statistics Once the results of the statistical analysis are known, it is important to report them in a fashion that is clear and consistent with the way other scientists will be reporting their results. Inferential statistics help us decide, for example, whether the differences between groups that we see in our data are strong enough to provide support for our hypothesis that group differences exist in general, in the entire population. ���8V�&Ő�N��kB�Ik�3K��n.�L"���8 �f�;b���Y]JJXAf"o��f��MdLf� dmT6:��$�����t��xqE�K$��*�ˡ���`�T�&�� the results of the analysis of the sample can be deduced to the larger population, from which the sample is taken.
