Hey everybody, I need some help with my dissertation regarding bell curve graphs. Let me explain, I have carried out a questionnaire where the participates had to answer either ‘strongly agree, agree, somewhat agree, somewhat disagree, disagree and strongly disagree’. Each one of these options had a number assigned to them; 1, 2, 3, 4, 5, 6. For question one; 58 people strongly agreed (1) 25 people agreed (2) 12 people somewhat agreed (3) 10 people somewhat disagreed (4) 4 people disagreed (5) and 1 person strongly disagreed (6) The average (Ø) answer to question one was 1.91 and the standard deviation (±) is 1.22. I need to analysis my statistics, is it possible to create a bell curve graph with the type of data I have collected?

Take the graph of a standard normal. Change the scale by widening by a factor of 1.22. Lower the height by the same factor. Finally shift the center to 1.91.

I have attached a image of the described question. Does this look correct? and which one of the two is better?
