   Question

   A researcher has drawn a sample among children who have been playing a musical instrument for five years. He investigated whether the number of hours a child exercised with the instrument per week influenced the number of musical exams that the child had achieved (in total there were 8 exams, the first exam being the easiest and the last exam the most difficult; graph expressed with level of musical skill). The children were also asked if their parents were very strict when it came to practicing (whether or not ‘pushy’/ strict). What does the regression chart below show ?

   

   
   
   1. TRUE: The more a child exercised, the more music exams the child made. This relationship was stronger for the children who had strict parents compared to the children who did not have strict parents.
   2. FALSE: The more a child exercised, the more music exams the child made. This relationship was stronger for the children who did not have strict parents, compared to the children who had severe parents.
   3. FALSE: Children with strict parents received more music exams than the children who did not have strict parents. This relationship was stronger for children who exercised a lot, compared with children who did not exercise very much.
   4. FALSE: Children with strict parents had more music exams than the children who did not have strict parents. This relationship was stronger for children who practiced little, compared with children who practiced a lot.
   
   

   Solution

   The right answer is; he more a child exercised, the more music exams the child made. This relationship was stronger for the children who had strict parents compared to the children who did not have strict parents.
