Imаgine thаt а researcher is interested in studying the effect оf Distractiоn оn Driving Performance. The researcher creates a closed-course for safety reasons, and decides to count the number of cones hit while doing one of the following: driving the course while trying to eat, and driving the course while solving math problems via text message. She puts the first 10 people who arrive for the experiment in the "eating" group, and the next 10 people who arrive in the "texting" group. She only has one day to conduct this experiment and rain is predicted between noon and 8 pm on the day of the experiment. Nevertheless, she must collect here data. Answer the following questions using what you learned from the textbook and the videos on scientific thinking.: 1) Describe the independent variable for this experiment in detail. Has this researcher created the independent variable correctly? If not, explain why not specifically. 2) What is the Dependent Variable in this example? What is this researcher's specific definition of her Dependent Variable? 3) Write the NULL and Alternative Hypotheses for this experiment. 4) Are there any other major problems you want to tell this researcher about? If so, explain the problem(s) in detail. 5) As discussed in your Research Design chapter, write at least 2 obvious confounding variables for this experiment.
