An Experiment Was Done to Look at Whether There Is

Multiple Choice

An experiment was done to look at whether there is an effect of the number of hours spent practising a musical instrument and gender on the level of musical ability. A sample of 30 (15 men and 15 women) participants who had never learnt to play a musical instrument before were recruited. Participants were randomly allocated to one of three groups that varied in the number of hours they would spend practising every day for 1 year (0 hours, 1 hours, 2 hours) . Men and women were divided equally across groups. All participants had a one-hour lesson each week over the course of the year, after which their level of musical skill was measured on a 10-point scale ranging from 0 (you can't play for toffee) to 10 ('Are you Mozart reincarnated?') .
-An ANOVA was conducted on the data from the experiment. Looking at the output below, which of the following sentences is correct?

A) There was no significant main effect of gender.This means that overall, when we ignore the number of hours spent practising, the gender of the participant did not have a significant effect on the level of musical skill.
B) There was no significant practice ? gender interaction effect, indicating that if we ignore the gender of the participant, the number of hours spent practising did not significantly affect the level of musical skill.
C) There was a significant main effect of gender.Looking at the group means, we can see that women achieved a significantly higher level of musical skill (M = 5.53) than males (M = 4.87) .
D) There was a significant main effect of practice.This means that men and women significantly differed in the amount of practice that they did.
