angularjs - The correct definition of data -

i have code, when run error of "referenceerror: data not defined" have defined data in several ways nothing seem correct. thing when think data declared in api (no?).. appreciate help..

app.service('statisticsservice',         ['apiclient', '$q', '$rootscope', '$timeout',             function (apiclient, $q, $rootscope, $timeout) {                  var self = this;                   self.getstatisticsfromserver = function (data) {                      var deferred = $q.defer(); //1                       apiclient.getstatstopmeeters(data)                              .then(function (response) { //2                                  console.log('externalapiconnect', response);                                   if (response.data.length === 0 || response.result !== "success") {                                     // todo: show error                                     deferred.reject(response);                                 }                                  var stats = response.data;                                  stats = self.getuserprofiles(stats);                                  deferred.resolve(stats);//3                              }                              , function (error) {                                 deferred.reject(error);                                 console.error(error);                             });                      return deferred.promise; //4  };                         self.getuserprofiles = function (stats) {                         var deferred = $q.defer();                          var emails = [];                          (var = 0; < stats.length; i++) {                             emails.push(stats[i].email);                         }                          console.log(emails);                          var data2 = {                             token: data.token,                             profile_emails: emails                         };                          apiclient.getuserprofiles(data2).then(function (response2) {                              console.log('getuserprofiles', (response2));                              if (response2.data.length === 0 || response2.result !== "success") {                                 // todo: show error                                 deferred.reject(response2);                             }                              var stats = response2.data;                              deferred.resolve(stats);//3                          }                          );                     };              }]);
