In the plant experiment, the independent variable could be fertilizer—some plants will get fertilizer, others will not. The scientists change the amount of the independent variable (the fertilizer) to observe the effects on the dependent variable (plant growth).
What is the independent variable in a plant growth experiment?
An independent variable is the variable the experimenter controls. Basically, it is the component you choose to change in an experiment. This variable is not dependent on any other variables. For example, in the plant growth experiment, the independent variable is the light color.
What is the independent variable in the experiment described above?
An independent variable is the variable that is changed in a scientific experiment. Independent variables are the variables that the experimenter changes to test their dependent variable. For example, a scientist is testing the effect of light and dark on the behavior of moths by turning a light on and off.
What are the dependent and independent variables for the plant experiment?
In this plant growing experiment, the scientist is trying to figure out if providing more fertilizer will allow the plant to grow taller. The independent variable (IV) is the “manipulated” variable that the scientist is changing and the dependent variable (DV) is the “responding” variable that the scientist measures.
What is the independent variable in an experiment?
Independent variables (IV): These are the factors or conditions that you manipulate in an experiment. Your hypothesis is that this variable causes a direct effect on the dependent variable. Dependent variables (DV): These are the factor that you observe or measure.
What is the independent variable in?
Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable.
Will a plant grow higher with more light independent variable?
Sunlight is related to plant growth. If the amount of sunlight is increased, then plant growth will increase. The hypothesis that plant growth increases as the amount of sunlight increases was supported by the data.
What is the dependent variable in the experiment above *?
The dependent variable is the variable that is being measured or tested in an experiment. 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores, since that is what is being measured.
How do you identify an independent variable?
The easiest way to identify which variable in your experiment is the Independent Variable (IV) and which one is the Dependent Variable (DV) is by putting both the variables in the sentence below in a way that makes sense. “The IV causes a change in the DV. It is not possible that DV could cause any change in IV.”
What are independent and dependent variables examples?
Independent variable causes an effect on the dependent variable. Example: How long you sleep (independent variable) affects your test score (dependent variable). This makes sense, but: Example: Your test score affects how long you sleep.
What variable is the height of the plant depends on?
dependent variable
The dependent variable is the height of the plant, because you predict that the height is going to change DEPENDING on how much water the plant receives. Answer 2: An “Independent variable” can mean a lot of different things.
What are dependent variables for growing a plant?
The dependent variable would be the growth in height or mass of the plant. The controlled variables would be the type of plant, the type of fertilizer, the amount of sunlight the plant gets, the size of the pots, etc.
Which of the following describe an independent variable?
The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable.The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on the independent variable.
What is independent and dependent variable in biology?
Independent vs Dependent Variables
An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.
What is dependent variable in research?
Definitions. Dependent Variable. The variable that depends on other factors that are measured. These variables are expected to change as a result of an experimental manipulation of the independent variable or variables. It is the presumed effect.
Will a plant grow higher with more light?
Sugars fuel plant growth, so the more light a plant is exposed to, the more energy it will create and the faster it will grow.
Is growth an independent variable?
In the plant experiment shown in the Figure below, the dependent variable is plant growth. The variable that affects the dependent variable is called the independent variable. In the plant experiment, the independent variable could be fertilizer—some plants will get fertilizer, others will not.
Does light affect plant growth experiment?
Plants deprived of light will lose their color and die. The shoots exposed to “limited/no” sunlight had a yellow/white color due to the fact that photosynthesis could not occur. The lack of sunlight stunted photosynthesis and therefore the sprouts were not able to produce the chlorophyll needed to create a green color.
What is the independent variable in science quizlet?
An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment. You just studied 2 terms!
How do you identify variables in an experiment?
An easy way to think of independent and dependent variables is, when you’re conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.
What are examples of independent?
The definition of independent is someone or something that is free from the influence or control of another. An example of independent is someone who lives on their own and supports themself.
