Explain About the Possible Threats to Internal Validity.

Q. 1. Explain about the possible threats to internal validity.

 The possible threats can be dealt of told in 3 points as we can conclude form the study done,

They are as follows.

* Is the examiner's decision right?

* Are the adjustments in the autonomous variable in fact in charge of the watched variety in the subordinate variable?

* Might the variety in the reliant variable be owing to different causes?

Q. 2. Explain in brief the sources of error in communication studies and how to minimize them?

 The sources of error as follows

• Measurement questions.

• Participant

• Interviewer.

* Researchers/Interviewers can't help a business leader answer an exploration question on the off chance that they

1) select or make unseemly inquiries,

2) ask them in wrong request, or

3) use wrong moves and directions to evoke data.

* Interviewer blunder is mistake that outcomes from questioner impact of the member. It can be created by a few activities, for example,

1)failure to secure full member participation,

2)failure to record answers precisely and totally,

3)failure to reliably execute meeting systems,

4)failure to set up proper meeting environment,

5)falsification of answers,

6)inappropriate affecting conduct, and

7)physical nearness inclination.

*Participants cause blunder in two ways: whether they react (ability) and how they react.

*Three elements impact member investment:

- The member must trust that the experience will be wonderful and fulfilling.

- The member must trust that noting the study is advantageous.

- The member must release any mental reservations about support.

Q. 3. Define nonresponse error.

 A non-responsive error can be defined as following

Non-response errors happen when the study neglects to get a reaction to one, or potentially
