Javascript - calculate average from multid array

Hi,

How do I calculate the average of y?

var activity = [{
	name: 'activity',
	data: 
		[
		{name: 'one', color: '#2c2d2f', y: 12.00}, 
		{name: 'two', color: '#189e31', y: 78.4},
		{name: 'three', color: '#c1171d', y: 9.6}
		]
}]

		{name: 'two', color: '#189e31', y: 78.4},
		{name: 'three', color: '#c1171d', y: 9.6}
		]
}];

var total = 0;
var q = activity[0].data.length;
for(var i=0;i<q;i++) total += activity[0].data[i].y;
var avg = total/q;

alert(avg);
