TYPES OF VARIABLES There are 2 main types of variables: Independent Variable: The variable that is changed by the scientist; the ‘I control’ variable Dependent Variable: The variable that might change because of what the scientist changes –what is being measured proposed variables for a study (independent, intervening, dependent), drawing a visual model to identify clearly this sequence (conceptual framework), and specifying the measurement for variables. Intervening Variables Intervening variables are hypothetical internal states that are used to explain relationships between observed variables, such independent and dependent variables.

Intervening explains the relationship between the independent and dependent variable. Researchers in observational studies must include confounding variables (i.e., confounders) to keep the statistical results valid even if they are not the primary interest of the study. Experiments also have controlled variables. For example, if we want to explore whether high concentrations of vehicle exhaust impact incidence of asthma in children, … There must be a relationship or correlation between the independent and dependent variables.

But this relationship will be completed only if another variable intervenes – that is, the use of contraceptives. The intervening variable is a consequence of the independent variable and a determinant of the dependent variable, as shown in Fig. There must be no other intervening variable responsible for the causal relationship. When independent independent variable, there is an increase or decrease in the dependent variable also. In other words, the variance in dependent variable is accounted for by the independent variable. Dependent variable is also referred to as criterion variable. symbol (Y) for the dependent variable.

Studies analyzing dependent variables look at how and why they differ from one another. For example, we might find that match length (an independent variable) predicts youth well being (the dependent variable). For example, if the use of a particular teaching technique is the independent variable and mastery of the objectives is the dependent variable, then the language learning processes used by the subjects are the intervening variables.

Existence of such variable is essential to show the relationship between dependent and independent variables. It explains how or why there is a relation between two variables. It further explains that even though intervening, mediating, and moderating variables explicitly alter the relationship between independent variables and dependent variables, they help to explain the causal relationship between them.
