Question
Extraneous variables are I. Uncontrolled variables II. Manipulated variables III. Non manipulated variables IV. Distracting variables Codes :
The correct answer is
I, III & IV
Understanding Extraneous Variables
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.
Analysis of Statements
- I. Uncontrolled variables: Extraneous variables often exist outside the direct control of the researcher. They represent potential influences that were not managed. This statement is accurate.
- II. Manipulated variables: These are typically the independent variables that the researcher intentionally changes or varies to observe their effect. Extraneous variables, by definition, are not the ones being manipulated. This statement is inaccurate.
- III. Non manipulated variables: Extraneous variables are factors that exist within the study environment but are not actively manipulated or systematically varied by the researcher. This statement is accurate.
- IV. Distracting variables: Extraneous variables can obscure the true relationship between the independent and dependent variables, acting as 'distractions' or confounding factors. This statement is accurate.
Conclusion on Extraneous Variables
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
Types of variableLIST-II
MeaningA. 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.

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.
