how do i pass scope from controller to service in angularjs?

You can't inject $scope into services, there is no such thing as a Singleton $scope.

i want to pass a bound ng-model that sits in my view called ng-model="symbol_wanted" to the following service...

You can call the service and pass parameters this way:

    .factory('stockData', ['$resource', '$q', function ($resource, $q) {

    var factory = {
        query: function (value) {

            // here you can play with 'value'

            var data = $resource('http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20(%22YHOO%22)%0A%09%09&env=http%3A%2F%2Fdatatables.org%2Falltables.env&format=json', {}, {
                query: {
                    method: 'GET',
                    isArray: false
                }
            });
            var deferred = $q.defer();
            deferred.resolve(data);
            return deferred.promise;
        }

    }
    return factory;
}]);

So we call this service and get a promise back like this:

 stockData.query(value) // <-- pass value
        .then(function (result) {
        $scope.data = result;            
    }, function (result) {
        alert("Error: No data returned");
    });

BTW, I'd suggest you use `$http.get`:
