LESSON 4 - TYPES OF VARIABLES: INDEPENDENT, DEPENDENT, CONFOUNDING & MODERATING VARIABLES

When constructs are defined in measurable terms, they are called variables. Variables are measurable characteristic that assumes different values within a class of objects or events. Variables must vary. A construct that does not vary within a class of objects or events is called a constant. This lesson introduces you to the various types of variables in social science research. There are three main types of variables: Independent (IV) and dependent variables (DV) where the independent influences the dependent variable; we have confounding variables that confuses the primary relationship between IV and DV and moderating variables that mediates the relationship between IV and DV. Confounding variables are of two types: Intervening and Extraneous variables. This lesson will take you through these variables giving examples and revision questions to ease our understanding.

You didn't mentioned directional and non directionsl variables.

[deusathanas]

Great but I want to know other remain questions on IV and DV

[edwardtumwesige]

Thank you so much, Dr for clearly explaining the variables for me and others. Looking forward to more of your classes.

Hello Dr. I'm following up on the lectures slowly and I'm wondering, can I apply the knowledge I'm gaining here on Health sciences or is it specifically for Social sciences?

[hedwigwirsiym.]

A question about neutralizing variables Doc . In the case of the example you gave that of selecting students from a particular socioeconomic status, which means convenient sampling will be done...my question now is isn't this bias and discrimination against the other students who will not participate in the studies and who would have loved to? Or even vise versa?

[hellenombonya]

I would like to buy your book. Kindly share the cost.

[georgekimani]

Dr Lydia this is very informative and more importantly break it down in simplicity

[onesphorengabo]

A very important and well explained topic. Thank you Dr

[cathyhams]

how can we use a mixed method to identify variables in a study in order to come up with a conceptual framework

[adanmohamedhassan]

Thank you Dr. Lydiah very informative

[stephentialal]

Dr. Wambugu, does it add value to identify all the variables on a conceptual framework, ie The IV, confounding, moderating and DV or is it sufficient to have IV and DV only in a research project?

[richardessuman]

Dr. Thank you very much, I hope one day I become like you.

[HannatuAliyu-dw]

Thank you so much Dr. can you please break the 3 elements in a lay mans language.
