A china manufacturer is investigating market response to seven designs of dinner set. The main markets are the British and American. To get some idea of preferences in the two markets a survey of 100 British and 100 American women is carried out and each woman is asked to rank the designs in order of preference from 1 for favourite to 7 for least acceptable. For each country the 100 rank scores for each design is totalled. The design with the lowest total is assigned rank 1, that with the next lowest total rank 2, and so on. Overall rankings for each country are: Design ABC DEF British rank 1 2 3 4 6 7 American rank 4 1 5 2 7 Calculate the Spearman and Kendall correlation coefficients. Is there evidence of a positive association between orders of preference
