a variable is a feature that may vary within groups.
independent variable
It is a variable. The independent (manipulated) variable is the factor that is different between the control and experimental groups. The dependent variable is the difference resulting from the independent variable. The controlled variables are the factors that are not changed in the experiment between the control and experimental groups.
subject variable
The term you're looking for is "categorical independent variable." This type of independent variable consists of distinct categories or groups that allow researchers to compare differences among them, such as treatment groups in an experiment or demographic categories in a survey. By analyzing these differences, researchers can assess how variations in the independent variable affect the dependent variable.
No, age is not a nominal variable; it is typically considered a continuous or ordinal variable. Age represents a measurable quantity that can be expressed in years, months, or days, allowing for meaningful mathematical operations. While you can categorize age into groups (like "teenagers," "adults," etc.), the actual age values themselves have a clear order and numerical significance.

data type refers to the kind of value that is held by a particular variable. For ex: an int variable contains integer value, a string holds a alpha numeric value etc. variable refers to the name of a value using which we can refer to this value. Ex: public int age = 28; here int is the data type and age is the variable.
The variable that the experimenter deliberately changes across groups is the independent variable. This variable is manipulated to observe the effect it has on another variable, known as the dependent variable.

Independent variable: sickness Dependent variable: taste Controlled variables: type of sickness, age, gender, environment, type of food tasted

The term you're looking for is "categorical independent variable." This type of independent variable consists of distinct categories or groups that allow researchers to compare differences in dependent variables across these categories. Examples include variables such as gender, treatment groups, or types of interventions, which help in analyzing how these classifications impact the outcome measures.
Age can be considered an interval variable when it is measured in a continuous scale, such as years or months, where the differences between values are meaningful and consistent. However, it is more commonly treated as a ratio variable because it has a true zero point (birth), allowing for meaningful comparisons of magnitude. In certain contexts, age can also be categorized into intervals (e.g., age groups), but as a standalone measurement, it typically functions as a ratio.
