What best describes the relationship between a dependent variable and an independent variable in a scientific investigation?
The independent variable is what you are changing in the experiment to get varied results. The dependent variable is the result of what you have changed. So the dependent variable depends on the independent variable. For example, if you are experimenting with the effect of water on height of a plant, the different amounts of water that you give the plant is the independent variable. The height of the plant that you measure as the result of the water is the dependent variable.
Which of the following best describes a manipulated variable?
Fifteen turtles are fed iceberg lettuce and vitamins, while another fifteen turtles are fed only iceberg lettuce
How many variable events is it best to test in one experiment?
One
What statement best describes a primary source?
Someone who conducted the experiment.
What is the experimental variable and the control variable?
Ball sack

The variable that changes as the result of an experiment is a?
true or false : in order to get the best results from an experiment, change as many variables as possible within the experiment?
Which of the following is the best description of an independent variable?
An independent variable is the factor that is manipulated or changed by the researcher in an experiment to observe its effect on the dependent variable. It is the variable that is thought to cause a change in the dependent variable.
What is the dependent variable?
The dependent variable is the variable in the experiment that changes. For example if you were trying to figure out which of the three fertilizers works the best on flowers your dependent variable would be the fertilizer and the independent variable would be the flowers.

What statement best describes a controlled experiment?
A controlled experiment involves manipulating one variable (independent variable) while keeping all other variables constant, in order to observe the effect on another variable (dependent variable). This allows researchers to determine a cause-and-effect relationship between the variables being studied.
What is the dependent variable in an invisible ink experiment?
Well, honey, in an invisible ink experiment, the dependent variable is the thing you're measuring to see if it changes as a result of the invisible ink being used. So, it could be something like the visibility of the message under different conditions. Just remember, the dependent variable is the one that's dependent on the independent variable - it's like the sidekick to the main character in a cheesy detective show.
What is the dependent variable for which detergent works best?
The detergent which is being used because a dependent variable is what is being measured in the process. is dawn
Which of the following best describes a manipulated variable?
Fifteen turtles are fed iceberg lettuce and vitamins, while another fifteen turtles are fed only iceberg lettuce
Which word best describes 8z 5 18?
Ineqality
What graph is the best for an independent and dependent variable?
spread sheet
When the graph of best fit is a straight line the dependent and independent variables have what kind of relationship?
the dependent variable has one value and the independent variable has no value
What makes a good experiment versus a bad experiment?
A good experiment needs to be a fair test so to have a fair test you need to have a independent variable, a dependent variable and a controlled variable. Independent Variable: The thing you change Dependent Variable: The thing you measure Controlled Variables (there's usually more than one): The things you keep the same. For example if I have 3 kids and I want to find out who can open presents the quickest the independent variable: would be what kid is opening the presents the dependent variable: would be how quick the kids were so their time and the controlled variables: would be the size of the present they used and the wrapping paper on it. Also a experiment should be repeated twice for the best results and then averaged. A bad experiment wouldn't be a test for example changing what should be a controlled variable so if one kid had to open a bigger present than the other kid they would take longer than they would with the same size present so you wouldn't get good results.
