    1 The Nature of Variables

    Uploaded by

    Zia Zobel
    Variables can be qualities or characteristics that differ based on time or situation. There are three main types of variables: independent variables cause changes in another subject, dependent variables are affected by the independent variables, and extraneous variables unexpectedly impact the relationship between independent and dependent variables. For example, in a study of self-guided learning (independent variable) and test scores (dependent variable), participant variables like age or gender could influence the relationship between the two main variables.

    The Nature of Variables

    Variables

    • Are “changing qualities or characteristics” of persons or things like age, gender, intelligence,
    ideas, achievements, confidence, and so on that are involved in your research study.

    • Made up of the root or base word “vary” which means to undergo changes or to differ from,
    variables have different or varying values in relation to time and situation.

    Types of Variables

    • Independent variables are those that cause changes in the subject

    • Dependent variables are those that bear or manifest the effects caused by the independent
    variables.

    Variable Relationships

    • In a scientific way of studying cause-effect relationships, independent and dependent variable


    are part and parcel of the research because the first one is the cause; the second, the effect that you can
    subject to any form of measurement.

    • However, as you carry out the research, it is possible that one, two, or more variables or extra
    variables crop up to create an impact on the relationship between the independent and dependent
    variables. Being extra variables, they form this other type of variables called extraneous variables.

    • For example, in the case of SFG vs. IC, (the first as the independent variable; the second as the
    dependent variable) extraneous variables like age, gender, or personality traits may suddenly surface to
    create effects on the relationships of the two basic variables. Such extraneous variables are called
    participant variables if they refer to the moods, emotions, or intelligence of the subject; situational
    variables, if they pertain to nature of the place: smelly, chilly, cold, hot, spacious, and the like.
