A variable in research simply refers to a person, place, thing, or phenomenon that you are trying to measure in some way. The best way to understand the difference between a dependent and independent variable is that the meaning of each is implied by what the words tell us about the variable you are using.
Can a research question have two parts?
The more complex version is written in two parts; it is thought provoking and requires both significant investigation and evaluation from the writer. As a general rule of thumb, if a quick Google search can answer a research question, it’s likely not very effective.
What are the two types variables use in research?
Discrete and continuous variables are two types of quantitative variables: Discrete variables represent counts (e.g. the number of objects in a collection). Continuous variables represent measurable amounts (e.g. water volume or weight).
What are the two types of research question?
There are three types of research questions, namely descriptive, comparative and causal types.
What is the difference between independent and dependent variable in research?
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. The dependent variable is ‘dependent’ on the independent variable.
Is the type of variable?
Common Types of Variables. Categorical variable: variables than can be put into categories. Confounding variable: extra variables that have a hidden effect on your experimental results. Continuous variable: a variable with infinite number of values, like “time” or “weight”.
What are some examples of independent and dependent variables in research?
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 |
