What is meant by dependent variable?
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.
What is the dependent variable in an experiment?
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.
What is the best definition of dependent variable?
A dependent variable is what you measure in the experiment and what is affected during the experiment. The dependent variable responds to the independent variable. It is called dependent because it “depends” on the independent variable.
What is the meaning of dependent and independent variables?
The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.
What is an independent variable easy definition?
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.
What is variable in simple words?
A variable is a quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable.
How do you identify an independent variable?
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 is an example of an independent variable in science?
Time as an Example of an Independent Variable
| Question | Independent Variable (What I change) | Controlled Variables (What I keep the same) |
|---|---|---|
| How fast does a candle burn? | Time measured, in minutes | Use same type of candle for every test Wind—make sure there is none |
Is gender an independent variable?
Although social class, religion, gender, ethnicity and age are often treated as independent variables (e.g., factors, forces, structures) and invoked as causal explanations for various outcomes, this paper approaches these constructs in more distinctive, humanly-engaged terms.
What type of variable is used at home internet?
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 type of variable is a count?
A count variable is discrete because it consists of non-negative integers. Even so, there is not one specific probability distribution that fits all count data sets.
What type of variable is annual income?
An interval value with a true and attainable value of zero is a ratio variable. e.g. annual income in $, temperatures, time of day, elevation. Ratio Variables.
What type of variable is month?
What type of variable is ‘month’? The correct answer is c) Categorical. This is because months of the year are divided into distinct categories.
What type of variable is occupation?
Occupation is a priority 3 variable.
What is the difference between qualitative and quantitative variable?
Quantitative Variables – Variables whose values result from counting or measuring something. Qualitative Variables – Variables that are not measurement variables. Their values do not result from measuring or counting. Designator values usually do not repeat in a table, but variable values often do repeat.
