how can i create poor , good and excellent output ?

so i have this scripts here that will calculate my averageAttention .

this is the fisrt script

     eSenseValues = new float[session.thinkGearEvents.Length];
       
       var cumulativeAttention : float = 0.0;
       
       for(var i = 0; i < session.thinkGearEvents.Length; i++){
         eSenseValues[i] = session.thinkGearEvents[i].attention;
         cumulativeAttention += eSenseValues[i];
       }

second script

       averageAttention = session.thinkGearEvents.Length > 0 ? cumulativeAttention / session.thinkGearEvents.Length : 100;

  

the problem now here is , if the averageAttention is 1 to 39 it will tell that the averageattention is poor and else if the averageAttention is 40 to 60 it will tell that the score is Average and then inset those code to the second script .how can i make this second script,? please help me
