A possible, but incorrect explanation of research results is called: 

Leave a Comment / June 2015 (II), MCQ (Question-Answer), Research Methodology, UGC-NET (Paper II) /

A possible, but incorrect explanation of research results is called:  (A) internal variable (B) confounding variable (C) independent variable (D) dependent variable Correct Ans: (B) Explanation:A confounding variable is a hidden factor in research that falsely appears to explain the results. It interferes with the relationship between the independent and dependent variables, creating confusion or

Which theories or designs eliminates the communication bias?

Leave a Comment / Dec 2014 (III), MCQ (Question-Answer), Research Methodology, UGC-NET (Paper III) /

Which of the following theories or designs eliminates the communication bias in a research project? Correct Ans: (D) Explanation:Researchers often struggle with bias when they conduct communication studies. That’s where the double blind theory plays a vital role. This method ensures both the participants and the researchers stay unaware of key details—like which group receives

Control variable is used to remove

Leave a Comment / Dec 2014 (II), MCQ (Question-Answer), Research Methodology, UGC-NET (Paper II) /

Control variable is used to remove Correct Ans: (D) Explanation:Researchers use a control variable to remove unwanted influence from a study. In any research, many factors can affect the outcome. If left uncontrolled, these outside influences may distort the results. That’s where control variables play a critical role. A control variable stays constant throughout the

Any inconsistency produced by the instrument used will result in

Leave a Comment / June 2014 (II), MCQ (Question-Answer), Research Methodology, UGC-NET (Paper II) /

When a population is studied, any inconsistency produced by the instrument used will result in Correct Ans: (B) Explanation: In research, accuracy is crucial for reliable results. However, when a measurement instrument (such as a survey, scale, or test) produces inconsistent or inaccurate data, it leads to measurement error. This affects the validity and reliability
