Concepts are abstract ideas or general notions that represent phenomena or categories, such as "happiness" or "social status." Variables, on the other hand, are measurable elements derived from these concepts, typically used in research to quantify or analyze them, such as a happiness score or income level. While concepts provide the theoretical framework, variables allow for empirical testing and observation. Thus, concepts are broader and more qualitative, while variables are specific and quantitative.
variable
To determine your variable, start by clearly defining the research question or hypothesis you want to investigate. Identify the key concepts involved in your question, and then decide which of these concepts can be measured or quantified. Finally, classify your variable as either independent (manipulated) or dependent (measured) based on its role in your study, ensuring it aligns with your overall research goals.
Ex Post Facto (also called Causal Comparative Research) is useful whenever: • We have two groups which differ on an independent variable and we want to test hypotheses about differences on one or more dependent variables OR • We have two groups which already differ on a dependent variable and we want to test hypotheses about differences on one or more independent variables
The dependent variable.
The term used to describe the spread of values of a variable is "dispersion." Dispersion indicates how much the values in a dataset differ from the average or mean value. Common measures of dispersion include range, variance, and standard deviation, which provide insights into the variability and distribution of the data.

independent variable
A term is a constant, a variable, or combination of constants and variables. Examples: 7.13, 5x, where 5 is the coefficient of the variable xy, xyz, y, where the coefficient of the variable is assumed to be 1.

A concept is an idea or an abstraction that stands for something. A concept becomes a variable when it is made operational or when it can be counted, categorized, or observed. For example, job satisfaction is a concept, but, it becomes a variable when a definition is it attached to it that makes it measurable. You may ask a married person, "how satisfied are you with your job?" If you attach levels of satisfaction to it, then it becomes a variable. All variables are concepts when you can measure the concept. However, not all concepts can be variables. A concept that is not a variable is a concept that is not measurable.
Quantification is impossible until ideas and concepts are translated into variable that can be measured. e.g landforms shape
The only thing that should differ between experimental treatments is the variable being tested, also known as the independent variable. All other factors should be kept constant to ensure that any observed effects can be attributed solely to the variable being tested.
