Types of variables
1. The independent variables: They vary and have a presumed cause on another variable, the dependent variable. In an experiment, they are the manipulated variables. They are variables under the control of the experimenter. In a non-experimental study, they are the variables that have a logical effect on the dependent variable.
2. The dependent variable: They are the variables whose behaviors under controlled conditions are allowed to change in an organised manner.
3. Continuous variables: They are capable of taking on an ordered set of values within a certain. Variables that can take on an infinite number of possible values are called continuous variables.
4. Discrete variable: It is defined as a variable that can only take on finite number of values. All qualitative variables are discrete. Examples are the number of goals scored in a football match, the number of teachers in a school, the number of boys and girls in a class.
5. Latent variables: They are unobservable entities.
6. Active variables: They are manipulated variables.
