Scientific Method and Hypothesis Testing Whereas other types of human speculation are based on mere opinion science pursues and sticks to the facts Hypothesis and Perception The Roots of Scientific Method. What is research?. We ask questions all the time. Research is a formal way of going about asking questions. Ways of acquiring knowledge. Uses methodologies. Many different kinds (e.g. market research, media research and social research). Mary Mathias. SPS ITRT. What is the Scientific Method?. It’s the way scientists solve a problem.

This car will not start. 1.What are some possible reasons the car will not start?. 2.How would you test your guesses?. Scientific Method. 1. Observation: Notice there is a problem or question to be answered. Test Review. What is the six . step process used by scientists to solve problems. . Answer: Scientific Method. What is an aspect . of an experiment that changes as a result of the experiment and not because the scientist purposely changed it. Ho - this hypothesis holds that if the data deviate from the norm in any way, that deviation is due strictly to chance.. Alternative hypothesis. Ha - the data show something important.. Doing decision = accept/reject Ho (the decision centers around null hypothesis). Introduction. How do you tackle every day problems that occur in your life?. Objectives. After completing this lesson, you will be able to:. Compare and contrast theories and laws.. Describe the systematic . Experimental Design. What is Inquiry?. Begins with observations you make about the natural world, followed by a question.. What is causing that?. Use a variety of methods to answer the questions you raise.
