what is independent variable in thesis

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. Example: Independent and dependent variables. You design a study to test whether changes in room temperature have an effect on math test scores.

While the independent variable is the " cause ", the dependent variable is the " effect " - or rather, the affected variable. In other words, the dependent variable is the variable that is assumed to change as a result of a change in the independent variable. Keeping with the previous example, let's look at some dependent variables ...

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. It is the presumed effect. Independent Variable The variable that is stable and unaffected by the other variables you are trying to measure.

Here are several examples of independent and dependent variables in experiments: 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. You want to know which brand of fertilizer is best for your plants.

Definition: Independent variable is a variable that is manipulated or changed by the researcher to observe its effect on the dependent variable. It is also known as the predictor variable or explanatory variable. The independent variable is the presumed cause in an experiment or study, while the dependent variable is the presumed effect or outcome.

Extraneous variables (from Adjei, n.d.) While it is very common to hear the terms independent and dependent variable, extraneous variables are less common, which is surprising because an extraneous variable can destroy the integrity of a research study that claims to show a cause and effect relationship. An extraneous variable is a variable that may compete with the independent variable in ...

Independent and Dependent Variables, Explained With Examples. In experiments that test cause and effect, two types of variables come into play. One is an independent variable and the other is a dependent variable, and together they play an integral role in research design.

You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. ... Defining a scope can be very useful in any research project, from a research proposal to a thesis or dissertation. A scope is needed for all types of ...

In research, the independent variable is manipulated to observe its effect, while the dependent variable is the measured outcome. Essentially, the independent variable is the presumed cause, and the dependent variable is the observed effect. Variables provide the foundation for examining relationships, drawing conclusions, and making ...

In academic studies, these variables come together in the form of a cause-and-effect relationship, called dependent and independent variables. Dependent variables act as the effect in this relationship, and they vary heavily in the changes in the independent variable. The independent variable, on the other hand, is the cause, and its cause does ...

There are two key variables in every experiment: the independent variable and the dependent variable. Independent variable: What the scientist changes or what changes on its own. Dependent variable: What is being studied/measured. The independent variable (sometimes known as the manipulated variable) is the variable whose change isn't affected ...

A: A variable is anything that the study is measuring. Read through your source looking for the following characteristics or keywords to identify the dependent and independent variable in your study. Dependent variables: • Dependent variables depend on other variables. For example, if someone was studying the effects of pollution on asthma ...

Treatment and control groups are always independent variables. In this case, the independent variable is a categorical grouping variable that defines the experimental groups to which participants belong. Each group is a level of that variable. In observational studies, independent variables are a bit different.

The independent variable is the drug, while the patient's blood pressure is the dependent variable. In some ways, this experiment resembles the one with breakfast and test scores. However, when comparing two different treatments, such as drug A and drug B, it's usual to add another variable, called the control variable. ...

An independent variable is defines as the variable that is changed or controlled in a scientific experiment. It represents the cause or reason for an outcome. Independent variables are the variables that the experimenter changes to test their dependent variable. A change in the independent variable directly causes a change in the dependent ...

Definition and Examples. The independent variable is recorded on the x-axis of a graph. The effect on the dependent variable is recorded on the y-axis. The independent variable is the variable that is controlled or changed in a scientific experiment to test its effect on the dependent variable. It doesn't depend on another variable and isn ...

A variable is a characteristic that takes on different v alue so rc n ditf . Independent and dependent variables are descriptors of variables commonly used in educational research. The independent variables may be affecting the dependent variables, and in that sense, dependent variables depend on independent variables.

A theoretical framework is a conceptual model that provides a systematic and structured way of thinking about a research problem or question. It helps to identify key variables and the relationships between them and to guide the selection and interpretation of data. Theoretical frameworks draw on existing theories and research and can be used ...

Ordinal dependent variable: An ordinal variable is a categorical variable that has a specific order or ranking to its categories. Examples include education level (e.g., high school diploma, college degree, graduate degree), or socioeconomic status (e.g., low, middle, high). Interval dependent variable: An interval variable is a continuous ...

Freedman's work, Ramsden noted, suggested that density was no longer a primary explanatory variable for society's ruin. A distinction was drawn between animals and humans. "Rats may suffer from ...
