CASE STUDY

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

A1. Search for the information on the internet.

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

A2.  1) Because he saw that the amount of older people has donated more money than the younger people. 

        2) Because the data is only from one of the charity website so, on the other charity website it could be different. Also the money the younger people are donating is going up every year and if the trend goes on few years later the younger people will donate more money to the charity. And the chart only shows the amount of money and the not the activities the younger people do.  

Q3.What questions should they ask?

A1. 1) How old are you?

       2) How much money do you give to charity?

       3) How much time do you spend doing charity work?  

Q4. How many questions should they hand out? Who do you think should fill in their questions?

A4. They should hand out around 30 copies.   Adult and teenagers.   

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 of the data? What problems might there be if the data were typed incorrectly?

A5. 1)  Microsoft Excel.  

       2) They can go over the data again to check if they have the correct ones.

       3) Use a calculator and Spell Check for spelling.

       4) -The data won’t be counted

           - The result might be confusing because it’s different from what they expected.

Q6. What is the best way for Ellie and Mussie to present their result?

A6. They can present their result by using a table and charts.

                                                                                                                        

CASE STUDY

1.   They can look at the charity websites to see some information about which age does more charity work or do their own survey and ask both ages of adults and child.

2.   Mussie thinks he’s right because on the charity websites all show that adults do more charity work, Ellie thinks the data can prove him right because the websites only put the average of what they think is true if Ellie and Mussie want to know for sure they should conduct their own survey.

3.   They should ask these questions:

   How old are you?

   Do you do charity work often?

   How much do you donate to charities?

   What charity do you work with?

   What type of charity work do you do?

4.   They should hand out 100 questionnaires 50 to adults and 50 to children so they get different opinions.

5.   They should use Excel because it can sort data easily, and correctly with the formulas. They can check with an calculator, and the results would be wrong if you typed it incorrectly.

6.   The can use a pie chart to show the different percentages of the results.
