Is the dependent variable or the responding variable the one being tested in an experiment?
Yes. The dependent variable is the variable that is being measured during the experiment.
The one variable that is purposely changed to test a hypothesis is?
manipulated variable!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
What is mediator in experiments?
The mediator variable explains the relationship between the independent variable and the dependent variable.
Which variable of a well designed experiment might be affected by the factors?
dependent variable
What are the dependent variables in an experiment?
The factor that changes in response is called the dependent variable.
What affect does salt to freezing point hypothesis indipendent and dependent variable?
An "hypothesis" doesn't have independent and dependent variables until you design an experiment to test it. If you want to test the effect that salt in solution has on the freezing point of the solution, then the independent variable is the presence, absence, or concentration of the salt. The dependent variable is the freezing temperature you measure in each condition.
Does the independents variable or the dependent variable come first in a hypothesis?
independent
When can a hypoythesis be considered testable?
If there is an independent variable and a tangible dependent variable in it then it can be tested. A general form of a hypothesis would be: If the (independent variable) (verb)s, then the (dependent variable) will (verb). If it follows this format, it can be tested
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 is a prediction that states both indepedant and depend variables?
A prediction that states both an independent and a dependent variable is called a hypothesis. A hypothesis is stated as such: if "independent statement", then "dependent statement."
What is a dependent variable in a experiment that uses vinegar ang baking soda to blow up a balloon?
The independent variable is the type of liquid you mix with the yeast and the dependent variable is how big the balloon gets.
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 words should be used in a hypothesis?
Since an hypothesis is a statement based on whether the independent variable will have an effect on the dependent variable, it is best to use the words if and then. Example: If water is added to a plant then it would grow.
What do you need to perform a controlled experiment?
An independent and a dependent variable. A hypothesis. And lab coat, a white one.
The factor being measure in an experiment?
The dependent variable is monitored as the independent variable is changed. One is testing the effect of the independent variable on the dependent variable (ie effect of dissolved HClO on pH).
The difference between the independent and dependent variables?
Independent variables are variables that can be changed in an experiment, while dependent variables are variables that change as a result of an experiment. In other words, independent variables are what you change, and dependent variables are the results of the experiment.
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.
