Is throwing from the end better? Part 2.Suppose that we have 30 students willing to participate in our experiment to test center throw vs. end throw. We decide to have 15 students throw the pool noodle from the middle and 15 students throw the pool noodle from the end. 1.Suppose we let students pick which method they wanted to use. Why might this be a problem? Instead of letting students choose which method they will use, we can use random assignmentto select 15 students for the center throw and 15 students for the end throw. 2.Explain how you could use slips of paper to do random assignment. 3.Explain how you could use a random number generator to do random assignment. 4.What is the purpose of using random assignment? 5.What other variables will we attempt to keep the same during this experiment (list several)? Why? Many noodlers started chucking pool noodles from the end, until it was recently banned. Is end throwing actually better than the traditional center throw?
How to Experiment Well Multitasking? Or multiple distractions?Researchers in Canada performed an experiment with university students to examine the effects of multitasking on student learning. The 40 participants in the study were asked to attend a lecture and take notes with their laptops. Half of the participants were randomly assigned to complete other online tasks not related to the lecture during that time. These tasks were meant to imitate typical student Web browsing during classes. The remaining students simply took notes with their laptops. At the end of the lecture, all participants took a comprehension test to measure how much they learned. The results: students who were assigned to multitask did significantly worse (11%) than students who were not assigned to multitask. 1. Describe how the researchers could have carried out the random assignment. 2. Explain the purpose of random assignment in this experiment. 3. Identify one variable that the researchers kept the same for all subjects. Provide two reasons why it was important for the researchers to keep this variable the same. QuickNotes
