4.0 modeling

1) How could Mussie and Elli find out whether older people do more for charity than younger people?
They can do street interview, chat online system (e.g. Facebook), asking teacher and classmates at school, interview old age home, etc.

2) Why does Mussie think that these data prove him? Why might Ellie think that these data do not him right?
For Ellie answer is that the information might be not true.
For Mussie answer is that the data has shown him the acceptable answer.

3) What question should they ask?
• Who are you?
• How often do you donate money to the charity?
• What types of charity do you donate to?
• How much money do you donate to the charity usually?
• Do you do charity work?
– If yes: How long do you spend time doing in charity events?

4) How many questionnaires should they hand out? Who do you think should fill in their questionnaire?
I think they should hand out 45 copies first, and if it went out within the first 3 to 4 days. I think the next time they reprint should be 53 copies. Also this questionnaires are every one (but not for the babies, because they will not understand a word if he/she receive the question sheet).

Q5: WHICH SOFTWARE COULD MUSSIE AND ELLIE USE TO PUT ANSWERS INTO THE COMPUTER? HOW CAN THEY CHECK THAT THE DATA ARE CORRECT? HOW COULD THEY REDUCE THE NUMBER OF ERRORS IN THE DATA? WHAT PROBLEMS MIGHT BE IF THE DATA IF TYPED INCORRECTLY?

ANSWER: THEY COULD USE EXCEL TO PUT THE ANSWERS IN. THEY'LL CHECK THE DATA BEFORE PUTTING IT ONTO THE SPREADSHEET. THEY RESTRICT THE COMPUTER TO THEMSELVES BECAUSE IF THE DATA WAS TYPED INCORRECTLY, THEY MIGHT GO INTO THE WRONG CONCLUSION.

Q6: WHAT IS THE BEST WAY FOR ELLIE AND MUSSIE TO PRESENT THE RESULTS?

ANSWER: THEY CAN USE A PIE CHART TO SHOW THEIR RESULTS IN PERCENTAGE
