Problem Solving 1. Ten candidates for a beauty pageant were rank for best in swim suit attire. Two groups of evaluators judge differently. Find the Kendal's rank correlation coefficient. Is there significantly association between the two groups of evaluators? Group 1 Group 2 Use the formula: 2 T - C-D Where: N C is the number of concordant pairs, 5 Critic D is the number of discordant pairs. 4 T is the Kendall rank correlation coefficient n is the number of observations Statistical Significance: Z 8 7 - 3"tau" nin-1) 7 6 (2(2n+5) 7 9 10 10 9 Test Type Significance Level 0.1 0.05 0.025 0.01 One tailed test # 1.28 # 1.645 $ 1.96 #2.33 Two tailed test * 1.645 # 1.96 +2.33 #2.58 2. What will happen to the Kendal's rank correlation coefficient if the Group 3 rated the candidates instead of Group 2? Increase or decrease? Show your solution
