In this task, you are to ponder...
Among the 4 graphs (Line Graph, Bar Graphs, Pictograms, Pie Charts), one of the graphs that is NOT appropriate to represent the information?
- Can you identify the one that is not appropriate?
- Why do you think it's not appropriate?
- What makes you think the 3 remaining graphs are appropriate?
With reference to the feedback provided in your postings, are you able to answer to the above questions?
The following have not attempted this activity. Please post your response in a separate post (as required in the eLearning lesson instructions):

The other graphs are appropriate as they show the number of places which are sunny, windy, cloudy, etc.
*Sorry for submitting this late as I had forgotten about this part.
In the TWO tasks, you were to analyse data presented and use spreadsheet (e.g. Numbers, GoogleSpreadsheet, MS Excel) to compute data and generate charts.
The files are provided in 3 formats (PDF, MS EXCEL and GoogleSpreadsheet).
You may choose to use any type where appropriate and present your answers in a shared GoogleDocument.
Here are resources to those who need help to plot the charts:
- iWork - Numbers
- Numbers '09: Creating a chart from table data
- Create a chart or graph using GoogleSpreadsheet
- Youtube clip 1: Numbers '09 - Create and Edit Charts
- Youtube clip 2: Creating Charts in iWork 09 Numbers (MacMost Now 460)
Those who have not handed in, the deadline has been extended to Thursday (29 March 2012).
You may check the status of submission at GoogleSite > Mathematics > Class Page
I think that the line graph is inappropriate in this situation as a line graphs are used to represent one factor over a certain period of time . However this graph is used to represent different factors.
i think that the pie chart is irrelevant because it only shows the percentage and we still need to calculate but the others show the number of countries so they are more relevant
