Understanding Variables in Research

The video tutorial covers practical research for senior high school, focusing on the nature and types of variables. It includes interactive true or false activities, definitions, examples, and discussions on various variable types, such as nominal, ordinal, interval, and ratio. The lesson also explores additional variable types like independent, dependent, extraneous, and control variables. The session concludes with learning tasks, assessments, and references.

What is an independent variable?

• A variable that is manipulated by the researcher.

What are extraneous variables?

• Variables that are always controlled.
