question 13

Multiple Choice

We took a sample of children who had been learning to play a musical instrument for five years. We measured the number of hours they spent practising each week and assessed their musical skill by how many of 8 increasingly difficult exams they had passed. We also asked them whether their parents forced them to practise or not (were their parents pushy?) . What does the graph suggest about children who spend approximately 1 hour practising a week?

• A)They were less affected by having a pushy parent than those that practised for 7 hours.
• B)They had less variability in their ability than those who didn't practise at all.
• C)On average, these children will be more musically skilled if they do not have pushy parents than if they do have pushy parents.
• D)On average, these children will be more musically skilled if they have pushy parents than if they do not have pushy parents.
