Page 2 of 9 1. What was the average number of correct responses (out of 8) for your class's Western participants? What was the average number of correct responses for your class's non- Western participants? For Western participants, there were a total of 61 participants. Number of participants' correct response (out of 61) for: Question 1 = 44 Question 2 = 45 Question 3 = 49 Question 4 = 19 Question 5 = 33 Question 6 = 48 Question 7 = 40 Question 8 = 25 Therefore, total number of actual participants' correct responses = 44+45+49+19+33+48+40+25 = 303 To express average number of correct response out of 8 = 303/61 = 4.97 For non-Western participants, there were a total of 59 participants.
Number of participants' correct response (out of 59) for: Question 1 = 25 Question 2 = 42 Question 3 = 44 Question 4 = 17 Question 5 = 24 Question 6 = 44 Question 7 = 19 Question 8 = 14 Page 3 of 9 Therefore, total number of actual participants' correct responses = 25+42+44+17+24+44+19+14 = 229 To express average number of correct response out of 8 = 229/59 = 3.88 (< 4.97) 2. What was the average difficulty rating (out of 4) for your class's Western participants? What was the average difficulty rating for your class's non-Western participants? For Western participants, Response Option 1 - Extremely Difficult 0 2 - Quite Difficult 7 3 - A Little Difficult 28 3*28 = 84 4 - Not At All Difficult 26 Number of Responses Total of Product = 0+ 14+ 84 + 104 = 202 Total number of participants = 61 Average difficulty rating out of 4 = 202/61 = 3.31 Product 1*0= 0 2*7 = 14 4*26 = 104
