Describing Graphs

Here is how your are going to organize your answer using the graph you created for your homework:


1 Introduction (Here you say what the diagram is about. )

The pie chart is about the pets in Year 7. The chart is divided into 4 parts and each part represents one class of Year 7.

2 Message of the diagram

The largest number of pets are in form 7GI. There are 16 pets.
The second largest number of pets are in form 7HK. There are 8 pets.
So there are more than twice as many pets in form 7GI.
The chart shows that there are only 2 pets in form 7CS and 3 in form 7VR.

3 Conclusion

So we can say that the most pets of Year 7 are in form 7GI and the least in form 7CS. There are more than 50 per cent of all the pets in one form - form 7GI.

Summary

After, analyze the information you created.

Line Graphs

Summarize the graph below with your group. Use the tips below to help you.

Top tip for writing:

1. Start by writing exactly what the graph shows, and the time period.

2. Describe the changes as precisely as you can. Use data and numbers of the chart.

3. Compare the information. Talk about differences or similarities between the groups shown.

4. Conclude by writing what the main trends or changes are.

A graph that uses points connected by lines to show how something changes in value (as time goes by, or as something else happens).

The line graph shows the value of Sarah's car according to the year. What can you conclude?

Summarizing Graphs

The graph used is a pie chart and shows the eye color of students in a class. The chart considers three colors of eyes: brown, blue and green.

The graph shows that half of the students in the class have blue eyes. The other half of the class have brown or green eyes. However, there are more students with brown eyes than green eyes.

In conclusion, the majority of students have blue eyes, followed by brown eyes and the fewest students have green eyes.

The graph used is a bar chart and shows how long animals can hold their breath. It considers whales, dolphins and seals. The time used is minutes and the range is from 0 to 20 minutes.

From the graph we can see that whales can hold their breath for almost 20 minutes, Dolphins can hold their breath for 12 minutes and seals for 7 minutes.

In conclusion, whales can hold their breath for the longest period and seals for the shortest period.
