Q1: How could Mussie and Ellie find out whether older people do more for charity than younger people?

A1: They can find it out by searching in the search engine.

Q2: Why does Mussie think that these data prove him right? Why might Ellie think that these data do not prove him right?

A2:  Mussie thinks that this data prove him right because it is showing that adult donate more money than children do. Ellie thinks that this data prove her right because it’s only one part of the charity and the total amount of children donating are increasing

Ø     Do they donate money to the charity?

A4: They have to hand out at least 30 questionnaires. I think students and their parents should fill in their questionnaire.

Q5: Which software could Mussie and Ellie use to put the answer 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 there be if the data were typed in incorrectly?
