What are hypotheses supported in science?
The basic idea of a hypothesis is that there is no predetermined outcome. For a solution to be termed a scientific hypothesis, it has to be an idea that can be supported or refuted through carefully crafted experimentation or observation.
How variable is manipulated in experimental research?
Experimental manipulation describes the process by which researchers purposefully change, alter, or influence the independent variables (IVs), which are also called treatment variables or factors, in an experimental research design.
What is a manipulative experiment?
Manipulative Experiments In a manipulative field experiment, the investigator first alters levels of the predictor variable (or factor), and then measures how one or more variables of interest respond to these alterations. These results are then used to test hypotheses of cause and effect.
What are three possible controls for this experiment?
What are three possible controls for this experiment? Student answers will vary. Possible answers include, the ramp, the ball, the distance on the ramp from which the ball is released, the amount of air resistance, and so on.
