Is Sunlight An Independent Variable? - Fixanswer

In this case,

the amount of light that the plant receives is changed

. This is the independent variable. … The amount that the plants grow depends on the amount of sun they get. The independent variable is what you change, and the dependent variable is what happens because of the change.

Is sunlight a controlled variable?

Each plant is exposed to an equal amount of sunlight, so

sunlight is the control variable

.

Is light dependent or independent variable?

Independent

and Dependent Variable Example

The brightness of the light is controlled by the scientist. This would be the independent variable.

What variable is sunlight?

In this case, the number of hours of sunlight is

the independent variable

and the height of the plant is the dependent variable, because the change in the height depends on the hours of sunlight, not the other way around.

Is time an independent variable?

Time is

a common independent variable

, as it will not be affeced by any dependent environemental inputs. Time can be treated as a controllable constant against which changes in a system can be measured.

Is age an independent variable?

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. Other factors (such as what they eat, how much they go to school, how much television they watch) aren’t going to change a person’s age.

Is water salinity a dependent variable?

VARIABLES: The independent variable is the different amounts salt that will be added to the water (what is done by the scientist). The dependent variable is

the boiling temperature of the water

(what is being measured). III: HYPOTHESIS: If salt is added to water then, the boiling temperature is lowered.

How do you identify independent dependent and control variables?

Independent variable – the variable that is altered during a scientific experiment.
Dependent variable – the variable being tested or measured during a scientific experiment.
Controlled variable – a variable that is kept the same during a scientific experiment.

Which type of soil is best for plants?

The ideal blend of soil for plant growth is called

loam

. Often referred to as topsoil or black dirt by landscape companies, loam is a mixture of sand, clay, and silt.

How do you control independent variables?

In a

controlled

experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. The researcher can operationalize (i.e. define) the variables being studied so they can be objectivity measured.

How do you identify a controlled variable?

Essentially, a control variable is

what is kept the same throughout the experiment

, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.

Can a control group be an independent variable?

The independent variable is

“controlled” or held constant in the control group

. A single experiment may include multiple experimental groups, which may all be compared against the control group. The purpose of having a control is to rule out other factors which may influence the results of an experiment.

What are the 3 types of variables?

These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables:

independent, dependent, and controlled

.

Is the dependent variable affected by the independent variable?

Independent variables are what we expect will influence dependent variables. A Dependent variable is

what happens as a result of the independent variable

. … A confounding variable, or confounder, affects the relationship between the independent and dependent variables.

What is dependent and independent variable in Research example?

In a study to determine whether how long a student sleeps affects test scores,

the independent variable is the length of time spent sleeping

while the dependent variable is the test score. … The independent variable in your experiment would be the brand of paper towel.
