• For the purpose of Åsa´s assignment, show the prices for the different yearmodels of Volvo 245 in an appropiate diagram.
• Åsa has heard that ”on the average the price of Volvos decreased with 8 000
kr each year.” Does this ”rule of thumb” agree with the values which are included in the in-vestigation?
• Can you find a similar or another ”rule of thumb” for the BMW?• If you were going to buy one of the car models, how could this investiga-
tion be of help to you?
When assessing your work, the teacher will consider the following:
• how clear, informative, and distinct your diagrams are.
• how well you motivate if the ”rule of thumb” for Volvo agrees with the investi-gation or not.
• how well you motivate your ”rule of thumb” for the BMW or the absence of a”rule of thumb” .
• How well you describe your usage of the investigation.
