Summary Introduction
Introduction:
A hypothesis is a primary step to initiate the scientific experiment. It is an explanation for a natural process, a particular observation, or specific condition tested through experimentation. It gives the purpose to initiate the experiment or to explore the area more thoroughly. A single study can provide more than one hypothesis.

A useful hypothesis typically accomplishes these two things:
Group of answer choices
it is falsifiable and clear
it clearly establishes a null hypothesis and it generates a testable prediction
it can be easily disproved and will be considered a theory if not disproved
it frames an experiment that can shed light on the observation and guides design of the experiment
Design a (hypothetical) experiment that adheres to the Scientific Method. Be sure to include all the necessary requirements at each step and give examples at all of the steps. Start with an observation, whether it's real or made up, state the null hypothesis, and design an experiment (including an experimental and control group, random sampling, sample size, and reproducibility) that will allow the student to reject or fail to reject the hypothesis, and state (hypothetical) 'actual' results and the appropriate conclusion to draw from those results.
Which of the following is not correctly linked?a. model: a representation of an object used in an experimentb. standard deviation: a form of statistical analysisc. principle: a theory that is not supported by experimental evidenced. data: the results of an experiment or observation

- A controlled experiment is one that proceeds slowly enough that a scientist can make careful records of the results. tests experimental and control groups in parallel. is repeated many times to make sure the results are accurate. keeps all variables constant.arrow_forwardThe 'control group' is an essential component of an experiment. This is because 1. A control group allows one to determine if a particular result is due to the experimental variable. 2. No, it's not essential in experimentation. A control group is not always necessary it depends on the experiment. 3. A control group allows for multiple variables to be tested at the same time. 4. A control group is required for the development of a prediction.arrow_forwardThe hypothetico-deductive method in science includes all of the following components except: designing a critical test for the hypothesis, as exemplified by Galileo’s test of falling objects unquestioning acceptance of Platonic Idealism, as practiced by certain medieval Benedictines continuous testing of the hypothesis by further inquiry, as emphasized by Socrates logical deduction (from a universal rule to particular predictions), as emphasized by Aristotle logical induction (from particulars to universals), as emphasized by Platoarrow_forward
