any one know “how to define the rating score”

[benjaporn Yamngamlour]

sometimes when we use the likert scale or any another interval scale ,  and we calculate the score from that .  How can we intreprete its meaning?

 

Example,  I use 5 = very good, 4= good , 3= neutral , 2= poor and  1 = so poor  and after ask the question to 100 people . I can calculate the score to 3.65  .  How can I mean this score?  It could be good or neutral .   And how can we judge that meaning?  from the normal curve ?
