Question

Imagine we were interested in the effect of supporters singing on the number of goals scored by soccer teams. We took 10 groups of supporters of 10 different soccer teams and asked them to attend three home games, one at which they were instructed to sing in support of their team (e.g., ‘Come on, you reds!’), one at which they were instructed to sing negative songs towards the opposition (e.g., ‘You’re getting sacked in the morning!’) and one at which they were instructed to sit quietly. The order of chanting was counterbalanced across groups. A one-way repeated-measures ANOVA was conducted and post hoc tests were selected. Looking at the output below, which of the following sentences regarding the pairwise comparisons is correct?

	a.	The first contrast revealed that soccer teams scored significantly fewer goals when their supporters did not sing compared to when they sang negative songs. The second contrast revealed that soccer teams scored a similar amount of goals when their supporters sang positive songs compared to when they did not sing.
	b.	The first contrast revealed that soccer teams scored significantly more goals when their supporters sang positive songs compared to when they did not sing. The second contrast revealed that soccer teams scored significantly fewer goals when their supporters sang negative songs compared to when they did not sing.
	c.	The first contrast revealed that soccer teams scored significantly more goals when their supporters sang positive songs compared to when they did not sing. The second contrast revealed that soccer teams scored significantly fewer goals when their supporters sang negative songs compared to when they sang positive songs.
	d.	The first contrast revealed that soccer teams scored significantly more goals when their supporters sang positive songs compared to when they did not sing. The second contrast revealed that soccer teams did not significantly differ in the number of goals scored when their supporters sang negative songs compared to when they did not sing.

Answer 1

here the answer is "The first contrast revealed that soccer teams scored significantly fewer goals when their supporters did not sing compared to when they sang negative songs.
