The process of random assignment occurs when she uses a computer program to randomly split her class into two groups. This is the point at which students are assigned to either the hands-on teaching method or the lecture-based teaching method, which helps to control for any pre-existing differences between the students in the two groups.
Kelly is a science teacher. She is conducting an experiment to determine whether her students retain more information about physics when they conduct hands-on experiments as opposed to reading and listening to lectures. Kelly uses a computer program to randomly select half of the students in her class to assign to each teaching method. She uses hands-on teaching methods with that group. With the other half, she uses her usual textbook and lecture teaching method. At random intervals, she tests all of her students on the content they’ve learned, using the same test and testing methods. When does the process of random assignment occur in this experiment?(1 point) Responses when she tests her students at random intervals when she tests her students at random intervals when she designs her experiment when she designs her experiment when she uses hands-on lessons with one group and lecture-style lessons with the other group when she uses hands-on lessons with one group and lecture-style lessons with the other group when she uses a computer program to randomly split her class into two groups
