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
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
What variable is the one that you can manipulate or change? It is sometimes called experimental variable

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.arrow_forwardThe null hypothesis is: That the measured value is zero That the proposed model is not correct and the measured factors have no effect on the pattern That the proposed model is correct and perfectly explains the pattern That the experiment is null and voidarrow_forward

Be sure to describe the main purpose and goal for each of these research methods.arrow_forwardYou observe that every time your neighbor, who always wears a yellow hat, walks out his front door, he gets dive bombed by a crow. From this observation, what is a testable hypothesis? What is your prediction based on your hypothesis? Please design an experiment to test this hypothesis and prediction. You must identify the independent and dependent variables, as well as at least 2 control variables, and your experiment must contain an experimental group and a control grouparrow_forward
