Research objectives are the goals of the research study. Research objectives specify the reason researchers are conducting research. For example‚ researchers may want to better understand the difference in pain scale results among subjects with a diagnosis of moderate traumatic brain injury. In this case the research objective would cause researchers to take steps to conduct scientific analysis to determine the variations in pain experienced between a group of individuals without a diagnosis of TBI

The models on the disbursement of modern humans include the Out of Africa hypothesis and the Multiregional Continuity hypothesis. The Out of Africa hypothesis explains that modern humans first evolved in Africa and then migrated out to Asia and Europe‚ displacing the archaic Homo sapiens already habituated there. In contrast‚ the Multiregional Continuity hypothesis explains that evolution of modern humans occurred regionally and without replacement‚ meaning that each continent’s archaic H. sapiens

The criteria for a hypothesis-based scientific study involves a few steps that should be followed in order. First‚ an observation is made and then a question should be posed about the observation that can be tested and possibly proved false. Next‚ we can make a hypothesis or educated guess about the result cause of the problem. We can then make a prediction on what may fix the issue. The final step would be to test our prediction to find the conclusion. The difference between a scientific based
