Question

A researcher is interested in studying how stress influences performance in a job interview. She has the first 100 participants engage in a stressful task before the interview (she has them take an unexpected difficult math test), and she has the second 100 participants engage in a non-stressful task (where they watch a short video clip of puppies playing), and then has them complete a mock-job interview.

1-Provide an operational definition for the dependent variable in this study. Some important information that needs to be included in your operational definition includes:
"what is the dv (how do you define it)?"
"how will you measure the dv?"
2- What is the confound for Scenario A

Answer 1

The dependent variable in this study is the performance in the job interview, which will be measured based on factors such as clarity of responses, body language, confidence, and overall impression. The confound for Scenario A is the difference in the level of stress experienced by the participants.

Step-by-step explanation:

1- Operational Definition of the Dependent Variable:

The dependent variable in this study is the performance in the job interview. It is defined as the ability of the participants to effectively answer interview questions and present themselves in a professional manner. The researcher will measure the dependent variable by evaluating factors such as clarity of responses, body language, confidence, and overall impression.

2- Confound for Scenario A:

The confound for Scenario A is the difference in the level of stress experienced by the participants. The first 100 participants engage in a stressful task before the interview, which might affect their performance in the interview itself. This makes it difficult to determine if any differences in performance are solely due to the stress or other factors.
