Bio 181 - Exam 1 {NCSU}, Top Questions and answers, 100% Accurate. VERIFIED. What is scientific inquiry? - -an understanding of how scientists study the natural world. What is the difference between discovery-based science and hypothesis testing? - -Discovery-based: observations, document observations, make a conclusion, science seeks for natural causes Hypothesis Driven: formal, use scientific method, hypotheses driven science Inductive reasoning - -Uses specific observations to develop general conclusions Bottom up (small to big) Deductive reasoning. - -Uses general principles to make specific predictions. Top down (big to small) Which one relates to hypothesis-driven science? - - Be able to define "hypothesis" and compare it to "theory" - -a possible explanation for an observation a theory implies a lack of knowledge or a guess while scientific theory is supported by much experimental evidence and scientific reasoning Be able to compare "hypothesis" to "prediction" - -Hypotheses should make predictions predictions test the validity of hypotheses. The more experimentally supported predictions a hypothesis makes, the more valid the hypothesis Know the parts of the scientific method and what is done in each. - -Observation - Hypothesis - Must be tested to determine its validity and tested in many different ways Prediction - Predictions provide a way to test the validity of hypotheses Experimentation - tests hypothesis, consists of a test experiment and a control experiment Conclusion - answer to the hypothesis Know the importance of careful observation in the scientific method - - Know the different types of variables and be able to define them. Dependent Independent Controlled - - Be able to identify variables if given a scenario - - Know control vs. experimental (treatment) group Why these groups are used - - Know the different types of data - - Quantitative vs
