function sort_by_average_rating(stores) {
    stores.sort(function (n1, n2) {
        var avg1 = 0, avg2 = 0;
        n1 = n1["ratings"];
        n2 = n2["ratings"];
        for (var i = 0; i < n1.length; i++) {
            avg1 += n1[i];
        }
        for (var i = 0; i < n2.length; i++) {
            avg2 += n2[i];
        }
        avg1 /= n1.length;
        avg2 /= n2.length;
        console.log(avg1 + "\t" + avg2);
        if (avg1 < avg2) return -1;
        if (avg1 > avg2) return 1;
        return 0;
    });
    return stores;
