Case study 4

Kevin and Ryan (Eagles)

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

Q3: What question should they ask?

A3: 
Ø     Do they donate money to the charity?
Ø     How much money did they donate to the charity?
Ø     How much time do they spend doing charity work?]

Q4: How many questionnaires should they hand out? Who do you think should fill in their questionnaire?

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?

A5:  They could use Microsoft Excel. They can check the questionnaires again. They can see that if they type in the answer carefully. They might come to the wrong conclusion when they look at the data later on.

Q6: What is the best way for Ellie and Mussie to present their results?

A6: They can make a pie chart to present their result
