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.
