Math CentralQuandaries & Queries


Question from Parnini, a student:

The following table shows the expenditure on different household items by a family. Draw a line graph for the following data:
Items : Food Rent Cloth Education Saving Others
Expenditure : 2000 2.500 1.500 1.200 4000 3.500

Hi Parnini,

A line graph doesn't make sense for data like this. A line graph is only appropriate when there are two columns of numbers, or at least two columns of numerically-related values. The items are not ordered
and can't really be related to each other.

Are you sure you don't want a bar graph or a pie graph? Both of those are good for this kind of data.
