Extraneous variables are I. Uncontrolled variables II. Manipulated variables III. Non manipulated variables IV. Distracting variables Codes :
Extraneous variables are factors in a research study that are not the independent variable but could potentially affect the dependent variable. Identifying these variables is crucial for ensuring the validity of research findings.
Based on the analysis, statements I, III, and IV correctly describe characteristics of extraneous variables. They are uncontrolled, non-manipulated, and can act as distracting influences in a study.
Therefore, the correct combination includes statements I, III, and IV.
| List I | List II |
| Variables | Characteristics |
| A. Experimental | I. Cannot be altered by researcher |
| B. Organismic | II. Uncontrolled but have significant effect on dependent variable |
| C. Assigned | III. Manipulated |
| D. Dependent | IV. Measurable, can't be manipulated |
| V. Is the presumed cause of dependent variable |
Given below are two statements, one labelled as Assertion (A) and the other labeled as Reason (R) :
Assertion (A) : Independent variables are manipulated by the researcher to see their effect on dependent variables.
Reason (R) : As they lead to the prediction of hypothesized extraneous variables.
In the context of the above two statements, which of the following statement is correct ?
Match the LIST-I with LIST-II
| LIST-I Types of variable | LIST-II Meaning |
| A. Extraneous Variable | I. A factor that could possibly influence the results and that is kept out of the study. |
| B. Dependent Variable | II. A kind of independent variable such as age, sex that cannot be manipulated. |
| C. Control Variable | III. A factor that could affect the relationship between the independent and dependent variables but that is not included or controlled. |
| D. Moderator Variable | IV. The effect of the independent variable. |
Choose the correct answer from the options given below:
Match the following :
| List – I (Variable) | List – II (Explanation) |
|---|---|
| a. Independent variable | i. It can take on any value from a range of values. |
| b. Dependent variable | ii. It is what a researcher wants to eliminate. |
| c. Continuous variable | iii. It is systematically varied by the researcher. |
| d. Control variable | iv. It is what the researcher wants to explain. |
