Katelyn the cat lover works at an animal shelter, and is trying to decide what kind of cat food to buy. She suspects that male cats like dry food the best, and female cats prefer wet food. She designed an experiment where each cat at the shelter can choose either wet food or dry food, and then records her results. Which factor is the independent variable in the study?

Monique the herpetologist wants to learn more about the salamanders that live in the creeks near her house. She is particular about what stream characteristics create the best habitat for salamanders. She thinks if the current of the stream is too fast, salamanders won't be able to live in it. She went around to all the creeks near her house and measured the speed of the current in meters/second (m/s) and counted all of the salamanders in a meter by meter area in each stream. Which factor is the independent variable in the study? Which factor is the dependent variable in the study? What types of variables does Monique have for her independent and dependent variables? What type of graph should Monique use to represent her data? Katelyn the cat lover works at an animal shelter and is trying to determine which type of food male and female cats prefer.

1. A response variable is: Applied to subjects by the researcher(s) Observed by the researcher(s) Both a and b None of the above 2. You are trying to determine what the best combination of diet and exercise provides the most weight loss. You decided to try three different diets (Atkins, Paleo, McDonalds 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. What is the response variable? a. Weight Loss b. Type of exercise c. Type of diet d. The combination of diet and exercise 3. You are trying to determine what the best combination of diet and exercise provides 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? 2 4 8 12 4. Consider an experiment where we use the amount of sugar in cereal to predict what shelf the cereal is placed on in a grocery store. What type of variable is the dependent variable? A. Quantitative B. Qualitative C. Continuous D. Discrete 5. Choose the variable(s) which is/are best described as qualitative: Height (in inches) Eye color Number of siblings IQ score Type of vehicle owned 6. 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. Check all that apply. The variable of whether or not the mice got cancer is Qualitative Continuous Dependent Independent Quantitative
