Answer 27

variables in the study whose values are believed to have an effect on the value of the response variables

Question 28

Treatment or factor levels

Answer 28

values or categories of the explanatory variable that are being considered in the study

Question 29

Extraneous variables

Answer 29

are those variables that may have an effect on the response variable but their effects are not of interest in the study

Question 30

How do researchers intervene/control the conditions that may affect the response variable?

Answer 30

The researcher intervenes by controlling the conditions that may affect the response variable by: 1. using a randomization mechanism in assigning the treatments 2. controlling the identified extraneous variables

Question 31

What will happen when the researchers intervene/control the conditions that may affect the response variable?

Answer 31

By doing so (intervening/controlling the conditions), the researcher can isolate the effects of the explanatory variable on the response variable and clarify the direction and strength of their relationship.
