The independent variable is the factor in an investigation that the scientist is changing.
The dependent variable is the factor which is measured.
All other variables, factors which could affect the experiment, are controlled, or kept the same.
For example, in an experiment to find out how light intensity affects bean plant growth, the independent variable would be the intensity of the light. The dependent variable would be the amount the plants grew. The controlled variables would be things like the temperature, the acidity of the soil, the amount of water given, the amount of CO2 in the air; in short, anything that could affect the results.
What else can I help you with?
Does a bi variate study have two dependent variables?
It does not have to. It is simply a study where two variables have a joint probability density function. There is no requirement for both variables to be dependent - one may be dependent on the other (which is independent).
What is the independent and dependent variables of a solar cell?
The answer to the question depends on what it is that you are trying to study.
Can a quantitative study have an independent and dependent variables?
Yes. The presumed cause is the independent variable and the presumed effect is the dependent varibale. Variablility in the dependent variable is presumed to depend on variablility in the independent variables. It is used more of a direction of influence rather than a cause and effect scenario. Ex. need for increased assistance is dependent on decrease in health. Health is the independent variable and assistance is the dependent.
Can a descriptive study have dependent and independent variables?
Yes, think about cause and effect when thinking about this issue. Even to describe or observe a phenomena.
What are the independent and dependent variables in a small size bottle of water cost 1.99 and a large size bottle of water cost 3.49?
Either- and most people are ignorant of this fact. If your study is about how the size of the bottle affects the price, then the independent variable is the size of the bottle and the dependent is the price. However, if your study is to determine how the price that you pay affects the size of the bottle, the independent variable is the amount of money and the dependent is the bottle size.

What is the full definition of multicollinearity?
Multicollinearity is when several independent variables are linked in some way. It can happen when attempting to study how individual independent variables contribute to the understanding of a dependent variable
Can a quantitative study have an independent and dependent variables?

What is the dependent and independent variables in a caffeine study?
The independent variable is the thing you are changing. The dependent variable is the result you are trying to measure. In a caffeine study, the amount of caffeine given to a subject would probably be the independent variable. The dependent variable would be what you are measuring, like moodiness, apparent energy, kidney function, etc.
Can a descriptive study have dependent and independent variables?
Yes, think about cause and effect when thinking about this issue. Even to describe or observe a phenomena.
Variables to study in thesis?
Variables to study in a thesis depend on the research question, but common ones include independent variables that impact the dependent variable. Examples include demographics, behavior, attitudes, and environmental factors. It's essential to specify these variables clearly to align with the research objectives.
What are independent variables?
Independent variables are factors in a study that are manipulated or controlled by the researcher in order to observe their effect on the dependent variable. They are variables that are believed to influence the outcome of an experiment or study.
Does the dependent variable change because of the independent variable?
Yes, the dependent variable is the one that is being measured or tested in an experiment, and its values are expected to change in response to manipulations of the independent variable. The relationship between the independent and dependent variables is the main focus of a scientific study.
A relationship between two or more variables that is shown in an observational study is a?
Correlation-apex (;
How is a controlled experiment different from an observational study?
In a controlled experiment, researchers manipulate variables to observe their effect on outcomes, while in an observational study, researchers observe natural variations in variables without manipulating them. Controlled experiments allow for stronger causal inferences compared to observational studies because they can establish cause-and-effect relationships.
What is a dependnt variable?
a dependent variable is the thing in your experiment you are testing or the thing that you are influencing. for example temperature. The independent variable changes on its on for example time. If you had a question : How long does it take for the water to reach 25c; the water temp is the dependent as you are measuring it, and the time is independent because you are not affecting it.
