1. in a study investigating the effect of exercise on body weight, what are the independent and dependent variables?

a both variables are independent b independent: exercise
dependent: body weight

Explanation:

Step1: Identify leading question (7a)

A leading question pushes for a specific answer. The question frames banning plastic bags as positive (protecting the environment), guiding respondents to agree.

Step2: Identify non-leading question (7b)

This question asks for factual, neutral data without pushing a specific response.

Step3: Define bivariate data (Q8)

Bivariate data involves two paired variables. Only option B tracks two variables (study hours, test scores) per student.

Step4: Define study variables (Q9)

Independent variable is the manipulated factor; dependent variable is measured outcome. Exercise is manipulated, body weight is measured.

Answer:

1. a. A. Yes

b. B. No

1. B. The relationship between hours of study and test scores among students.
2. B. Independent: exercise

Dependent: body weight
