Question

1.You are trying to determine what the best combination of diet and exercise to provide the most weight loss. You decided to try three different diets (Atkins, Paleo, McDonald's only), along with no dieting, and two different forms of exercise (Yoga, high cardio), along with no exercise. You try each combination possible, and track weight loss for each. How many independent variables do you have?

4.Consider an experiment where 10 mice were exposed to radiation from cell phones, and 10 mice were not. Whether or not the mice got cancer was observed for both groups. The variable “whether or not the mice got cancer” is: (Check all that apply)

a.Qualitative

b.Continuous

c.Dependent

d.Independent

e.Quantitative

Answer 1

Answer 1:

In the given scenario, there are two independent variables: type of diet and type of exercise . This is because in this case the researcher is interested in determining impact of different types of diet and exercise on the weight loss.

Answer 2:

In the given scenario, weight loss is a response variable. This is because in this case the researcher studies how different diets and exercises influence weight.

Answer 3:

The number of people in your household is an example of a Discrete variable. This is because the number of people will be finite and countable.

Answer 4:

The variable “whether or not the mice got cancer” is dependent and qualitative. It is dependent variable because in this case, researcher aims to identify whether radiation from cell phones is responsible for cancer in mice. It is qualitative data variable because in this case, mice will be classified into two categories "having cancer" and "not having cancer".
