TesT VaLue as The midPoinT on The TesT VariabLe Dan wants to determine whether students have a negative or a positive view toward current world leaders. He develops the World Leader Scale (WLS), which includes the names of 15 world leaders. He asks 100 students to identify the country that each leader governs and to rate the leader on a scale from 0 to 10, where 0 = a totally worthless leader, 5 = neither a worthless nor a worthy leader, and 10 = a totally worthy leader. A WLS score for a student is the mean rating for the leaders whose countries were correctly identified. Dan conducts a one-sample t test on the 100 WLS scores to determine whether the population mean is different from 5. The test value of 5 is chosen because a value less than 5 im- plies a negative view of world leaders, a score greater than 5 implies a positive view of world leaders, and a value of 5 implies neither a negative nor a positive view of world leaders. Dan's data file contains 100 cases, one for each student, and one test variable, the WLS scores. How do I plug it in to SPSS? What are the variables and values
