The “name game.” Refer to the Journal of Experimental Psychology—Applied (June 2000) study in which the “name game” was used to help groups of students learn the names of other students in the group, Exercise 7.120 (p. 434). [In the “name game” student #1 states his/her full name, student #2 his/her name and the name of the first student, student #3 his/her name and the names of the first two students, etc.] After a 30- minute seminar, all students were asked to remember the full name of each of the other students in their group, and the researchers measured the proportion of names recalled for each. One goal of the study was to investigate the linear trend between y = proportion of names recalled and x = position (order) of the student during the game. The data (simulated on the basis of summary statistics provided in the research article) for 144 students in the first eight positions are saved in the NAME2 file. The first five and last five observations in the data set are listed in the next table. [Note: Since the student in position 1 actually must recall the names of all the other students, he or she is assigned position number 9 in the data set.] Use the method of least squares to estimate the line Interpret the b estimates in the words of the problem.

the “simple name game,” in which a student states his/her name, and the names of all students who proceeded him/ her. Group 2 used the “elaborate name game,” a modification of the simple name game such that the students state not only their names, but also their favorite activity (e.g., sports). Group 3 used “pairwise introductions,” according to which students are divided into pairs and each student must introduce the other member of the pair. One year later, all subjects were sent pictures of the students in their group and asked to state the full name of each. The researchers measured the percentage of names recalled by each student respondent. The data (simulated on the basis of summary statistics provided in the research article) are shown in the table. Conduct an analysis of variance to determine whether the mean percentages of names recalled differ for the three name- retrieval methods. Use α= .05.
