What type of variable how Internet is used at home?
Income is a continuous variable. Household size and number of computers are discrete variables. (*) Occupation of head of household and type of internet connection are qualitative variables.
What is dependent variable in Research example?
The dependent variable is the variable that is being measured or tested in an experiment. 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 know if data is independent?
Events A and B are independent if the equation P(A∩B) = P(A) · P(B) holds true. You can use the equation to check if events are independent; multiply the probabilities of the two events together to see if they equal the probability of them both happening together.
What is a continuous independent variable?
CONTINUOUS (SCALE) VARIABLES: Measurements on a proper scale such as age, height etc. INDEPENDENT VARIABLE: The variable we think has an effect on the dependent variable. DEPENDENT VARIABLE: The variable of interest which could be influenced by independent variables.
What is an independent variable in a research study?
The independent variable (IV) is the characteristic of a psychology experiment that is manipulated or changed by researchers, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.
What is a categorical dependent variable?
Introduction. The categorical dependent variable here refers to as a binary, ordinal, nominal or event count variable. When the dependent variable is categorical, the ordinary least squares (OLS) method can no longer produce the best linear unbiased estimator (BLUE); that is, the OLS is biased and inefficient.
What are the independent and dependent variables in a hypothesis?
A hypothesis states a presumed relationship between two variables in a way that can be tested with empirical data. The cause is called the independent variable; and the effect is called the dependent variable.
What are some examples of independent and dependent variables in research?
The dependent variable is the effect. Its value depends on changes in the independent variable….Independent and dependent variables.
Research Question | Independent variable(s) | Dependent variable(s) |

How well do different plant species tolerate salt water? | The amount of salt added to the plants’ water | Plant growth Plant wilting Plant survival rate |
What are the types of independent variables?
Independent Variables: Other Names and Uses.
- A controlled variable.
- An explanatory variable.
- An exposure variable (in reliability theory).
- A feature (in machine learning and pattern recognition).
- An input variable.
- A manipulated variable.
- A predictor variable.
- A regressor (in regression analysis).
What is dependent variable in science?
The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on the independent variable. In an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable.
What is the difference between independent and dependent variable examples?
A dependent variable depends on an independent variable, while an independent variable depends on external manipulation. For example, when measuring how the speed of a car will affect the time it will take to reach a certain place, the time taken (dependent variable) depends on the speed (independent variable)….
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. Free from the influence, guidance, or control of another or others; self-reliant.
What is an example of continuous quantitative variable?
Examples of continuous variables are body mass, height, blood pressure and cholesterol. A discrete quantitative variable is one that can only take specific numeric values (rather than any value in an interval), but those numeric values have a clear quantitative interpretation.
Is plant height a dependent variable?
Plant height is the dependent variable that responds to the change in the independent variable. Each plant is exposed to an equal amount of sunlight, so sunlight is the control variable. They are also grown in the same sized pot and given an equal amount of water.
