Sufficient evidence?















Last week I asked my class the following question about this chart (taken from The Economist's Daily Chart online feature) :

Do you think these statements are TRUE or FALSE? Do you have enough evidence to verify each statement?

1. DVDs are cheap in China because they are all illegally copied.

2. The average Polish employee has to work longer than the average Indian employee in order to be able to afford a DVD.

3. DVDs are cheaper in Germany than in India.

4. The best films are made in France.

5. The currency used in Australia is dollars.

6. People in Japan like to watch DVDs.

7. The average US worker can earn enough money in 200 minutes to buy 4 DVDs.

Together we agreed that 2 and 7 are true, 3 is false, and we do not have sufficient evidence to comment on the other 4 statements. The students then wrote statements about other charts. Please comment on whether their statements are true, false, or impossible to comment on without further information.

The information seems to be posted without any link. Can we think a way to put the information together more logically.

Hi Cheng. They're supposed to be separate sentences, because it's an exercise in determining whether or not there is enough evidence to tell if they are true or false or not.

I asked everyone to write separate statements, not paragraphs. That will come next!
