Evaluation of the questionnaire

Our questionnaire contains 21 questions. During January and February it was done on the base of 75 individuals. We divided these 75 people into three groups:         

                        A) 25 people for young population till 19;

                        B) 25 people for mature population more than 20 years till 64;

                        C) 25 people for old population from 65 years.

For each question we put:        

                                            A) + for correct answer;

B) - for incorrect answer;

C) +/- for partly correct answer;

D) 0 for unanswered question.

We created table results and graphs in Excel for each question and for each group of people to represent results.
