Final answer:
The independent variable is the type of exercise, with high-intensity interval training as the experimental condition and low-intensity steady-state exercise as the control condition. When selecting participants, consider factors such as age and fitness level. Dividing participants randomly into a distracted texting group is not a good idea. Lurking variables such as health and motivation levels may interfere with the study, and blinding can be used to prevent participants from knowing which exercise type they are assigned to.
Step-by-step explanation:
a. Describe the explanatory and response variables in the study.
The explanatory variable in this study is the independent variable, which is the type of exercise. The response variable, on the other hand, could be various factors such as heart rate, calorie burn, or endurance.
b. What are the treatments?
The treatments in this study are the two different types of exercise: high-intensity interval training and low-intensity steady-state exercise.
c. What should you consider when selecting participants?
When selecting participants, it is important to consider factors such as their age, fitness level, and any pre-existing medical conditions. This would help ensure that the participants are representative of the population you are studying and that the results can be generalized.
d. Is dividing participants randomly into two groups, one to drive without distraction and one to text and drive simultaneously, a good idea?
No, this is not a good idea. Texting and driving is a dangerous activity that could put participants at risk of harm. It is unethical to knowingly expose participants to such risks.
e. Identify any lurking variables that could interfere with this study.
Some lurking variables that could interfere with this study include participants' overall health, diet, and motivation levels.
f. How can blinding be used in this study?
Blinding can be used in this study by ensuring that the participants are unaware of which type of exercise they are assigned to. This can be done by providing them with identical workout programs and instructions without revealing the intensity level.
