APPENDIX B Data Sets 759 (Complete data sets available at www.TriolaStats.com) Data Set 28: Course Evaluations Data are from 93 college student course evaluations (first five rows shown here). COURSE EVAL includes the mean course rating, PROF EVAL includes the mean professor rating, PROF AGE includes the professor age in years, SIZE includes the number of course evaluations per course, PROF BEAUTY includes the mean beauty rating based on the professor’s photo. Based on data from Andrew Gelman and Jennifer Hill, 2007, “Replication Data for Data Analysis Using Regression Multilevel/Hierarchical Models,” http://hdl.handle.net/1902.1/10285.

DEC BY FEM is decision (1 = yes) of female to date again, AGE FEM is age of female, LIKE BY FEM is “like” rating by female of male (scale of 1-10), ATTRACT BY FEM is “attractive” rating by female of male (scale of 1-10), ATTRIB BY FEM is sum of ratings of five attributes (sincerity, intelligence, fun, ambitious, shared interests) by female of male. Data for males use corresponding descriptors. Higher scale ratings correspond to more positive impressions.

All times are in seconds. The data for a single line are modeled from the actual times and are based on the assumption that all drivers enter a single waiting line and then move to one of the service stations as vacancies become available. Data observed and collected by the author. CAR is the sequence number for each vehicle based on arrival time. INTERARRIVAL TIME is the time (sec) since the previous car entered a line. SERVICE TIME is the time (sec) starting with a car entering a service bay and ending when it leaves the bay. TWO LINE WAIT - ACTUAL is the actual time (sec) a car spent waiting in a line. TWO-LINE BAY - ACTUAL indicates whether a car entered the left or right service bay. SINGLE LINE WAIT – MODELED is modeled by assuming that there was a single line feeding the two service bays. SINGLE LINE BAY - MODELED is the modeled service bay (left or right) that the car entered from a single line feeding two service bays.
