- create a scenario that includes an independent and dependent variable as well as a confound variable. What is the independent variable? How many levels are there for the independent variable? What is the dependent variable? What is the confound? How could this confound be fixed?arrow_forwardIf changing variable A causes variation in variable B, then variable A is identified or described by researchers as what variable? More specifically, is variable A associated with the cause or the effect, the independent or the dependent variable? A. Dependent variable B. Independent variable C. Co-dependent variable D. Methodological variablearrow_forwardStudents also often confuse the idea of Lurking Variable and Confounding Variable, but these are different but possibly related. This discussion is designed for students to help each other build a complete understanding, and clearly separate these as two distinct concepts. Discuss the similarities and differences between these, as well as what they imply for the conclusions of a research study.arrow_forward
