Which factor distinguishes the experimental group from the control group a conclusion a variable a hypothesis a theory?
The factor that distinguishes the experimental group from the control group is a variable. Specifically, it is the independent variable that is manipulated in the experimental group to observe its effect, while the control group remains unchanged to provide a baseline for comparison. A conclusion, hypothesis, and theory are related to the research process but do not serve this distinguishing purpose.

What is the variable setup in an experiment called?
The variable setup in an experiment is called the experimental design. This design includes all the factors and conditions that are manipulated or controlled in the experiment to test the research hypothesis.
What is the experimental variable?
The independent variable is the one variable that you change in your experiment
What is the name in an experimental design where the variable in which the researcher is trying to elicit a change?
The independent variable is the variable that the researcher manipulates or controls in an experimental design in order to observe its effect on the dependent variable.
What does experimental variable mean?
An experimental variable is the factor being tested or manipulated in a scientific experiment. It is often the independent variable that researchers change to observe its effects on the dependent variable. By controlling the experimental variable, researchers can examine the relationship between different variables and draw conclusions.
What is the difference between control and experimental variables?
Control variables are kept constant throughout an experiment to ensure that any changes in the dependent variable are due to the manipulation of the independent variable. Experimental variables, on the other hand, are the factors that are deliberately changed by the researcher to observe their effect on the dependent variable.
Is it sufficient to do a signle experiment to test a hypothesis?
define a experimental variable
How are hypothesis test?
By collecting data. Hypotheses are tested through experimentation, which can be manifest in an infinite amount of ways. The common ground in all hypothesis testing is that both a control (a group that is free of experimental manipulation in the studied variable), and an experimental group (a group with one experimental variable manipulated to test the effect of this variable) are needed to understand the question raised in the hypothesis.
The four main parts of an experiment?
First and foremost you must specify the hypothesis you are testing by the experiment. So you will have a testable null and alternate hypothesis. Next you will detail the resources and procedures used to generate the data needed by the tests specified by the hypothesis. Then using the described resources and procedures you will generate and record the data specified by the first two components. Next you will perform the analytic tests on those data, and record those results relative to the specifications made by your hypotheses. Following that you will write a summary of your results test and conclude whether your null hypothesis was shown to be not false based on you experimental results. Finally, you will write recommendations for further action and/or experiments based on your own experiment.
What are the most important controls needed in this experiment?
It is a conclusion,variable,a hypothesis,procedure,and data.
What is the variable setup in an experiment called?
The variable setup in an experiment is called the experimental design. This design includes all the factors and conditions that are manipulated or controlled in the experiment to test the research hypothesis.
What is the then part of the hypothesis and also the part that reacts to the manipulated variable?
The "then" part of a hypothesis is the prediction or expected outcome of the experiment based on the manipulation of the independent variable. It describes the specific response or change that is anticipated in the dependent variable as a result of the experimental manipulation.
What is the purpose of an chart?
Helps students organize identify independent variable, dependent variable, and constants in an experimental design. This information is then used to write an if/then statement for a hypothesis.
What does an IVCDV chart mean?
Helps students organize identify independent variable, dependent variable, and constants in an experimental design. This information is then used to write an if/then statement for a hypothesis.
What was needhams manipulated variable?
Needham manipulated the presence of air in his experimental flasks to test his hypothesis about spontaneous generation of organisms.
What is the differnece between experimental hypothesis and directional hypothesis?
The experimental hypothesis, if stipulated like this, does not imply to be taking any specific direction in its prediction. Hence we will be in a situation were it will only refer to as either, a difference or a correlation only, the experiemntal hypothesis. However, if we decide to give direction to the experimental hypothesis, then we will have to add some information to the stipulation focusing on whether we predict that the difference involved will specifically cause an increase or decrease of the dependent variable(s), the directional hypothesis.
What is the definition of dependent variable?
A variable in a research design that is free to change over a range of different experimental treatments. You have probably made a hypothesis that the dependent variable will change in some systematic way as the experimental treatments change. Examining the data that you generate will tell you whether or not your hypothesis is right.Term used in regressionanalysis to represent the element or condition that is dependent on values of one ormore other independent variables.Basically a dependent variable is an scientific term mostly used in science projects.Dependent variable means an variable that is changed by the expirment.
What is a synonym for experimental variable?
