Question

A research hypothesis proposes that consuming low carbohydrate diets results in increased weight loss. One group of participants follows a low-carb diet for 4 weeks, whereas a second group follows a high-carb diet containing the same number of calories for 4 weeks. The average number of pounds lost for each group is then is compared. What is the dependent variable?

Answer 1

The dependent variable is pounds lost for each group.

Explanation:

We are given the following in the question:

A hypothesis is done to measure the average number of pounds lost based on the fact whether a person follows a low carb diet or high carb diet.

Dependent and independent variable:

• The dependent variable depends on the independent variable.
• A change in dependent variable is due to change in independent variable.
• Independent is the free variable in the research hypothesis.

For the hypothesis:

Independent variable:

Participants of a group follows a low-carb or high carb diet for 4 weeks.

Dependent Variable:

average number of pounds lost for each group

Thus, the dependent variable is pounds lost for each group.
