The team will base its decision of which player to sign on four criteria: the player’s shooting ability, rebounding ability, ball handling skills, and attitude. Following is a survey of the three players’ college game statistics for their senior year: Although the coach can base some of her pairwise comparisons on these statistics, it is more difficult to assess attitude. She has interviewed each player, and she moderately prefers Keisha Jones’s attitude to Kathleen Taylor’s and strongly prefers Keisha Jones’s attitude to Natasha Franklin’s. Assume the coach’s role and develop pairwise comparisons for all four of the criteria and between the criteria. Use AHP to determine which player you would select.arrow_forward
