### Chap 16: Data Handling - Activity 3(b) Interpreting Line Graphs

Source of Information: Statistics Singapore. (2010, April 18). Statistics Visualiser. Retrieved from http://www.singstat.gov.sg/stats/stats.html#explorer.

Indonesia, China, Australia, Malaysia and India were Singapore’s top visitor-generating markets in 2009, accounting to more than 50% of total visitor arrivals for the year.

Increased air links and the growth of low cost carriers in the region contributed to the increase in visitor arrivals from countries such as Malaysia in 2009, mitigating the declines in visitor arrivals from other countries due to weak economic sentiments and the impact of Influenza A (H1N1).

Click HERE to view and access the interactive graph (as shown below) that shows the number of visitor arrivals from these 5 countries.
Note:
Make use of the interactive features of the graph (right click at the chart to explore) to draw out trends - for individual countries, as well as make comparisons between countries.

From the graphs,

(a) For each country, describe the variation in the data, starting from 1999 to 2009. Based on the data, would you predict the number of visitors for 2010 is going to be higher or lower than 2009? What makes you think it is higher or lower? [10 marks]
(i) Austrialia: ..... {i.e. your observation...}

(b) Make a comparison amongs the data from each country, the data from which country stands out? Why do you think there are more visitors from this country than others? Would you be able to briefly describe the possible purposes of visit by people from these 5 countries? [6 marks]

(c) What other observations or inferences you could make from the graphs? [Bonus: 4 marks]

Note: This is part of the daily work. All are to attempt.
You may refer to the example in Textbook Chap 16 (p176) to guide you in answering the question.

3. Dear Miss Loh,

I did not do this task because the graphs could not load so I did not have the information to complete this task. Thank you for your kind understanding.

4. a) I think it will be higher as it has been increasing consistently throughout the year.

5. a)It started to rise but dropped at 2003, it rose again at 2004 but stabilised at 2009.I think it will be lower as the rate it is increasing at is slowing down and it will likely drop in 2010.

6. (a) I think that the number of visitors will be lesser than the number of visitors than 2009. I think that it will be lesser than 2009 as the number of planes that are being manufactured should be lesser as there was a Global Financial Meltdown in 2007 to 2009. This caused many banks to go bust and other business such as manufacturing companies for planes etc. Thus some households may not have enough money to buy tickets to go on holidays.

7. (a)Australia: I think it will increase because it has been increasing since 1999 but decrease only once in 2003.Hence i think it is more likely that it will increase.

8. (a) I think it we can't make an accurate judgement as it is inconsistent and you never know when another finiancial crisis will strike.

9. Australia:The trend in the Line Graph is that the visitors are increasing and thus wil most likely continue to rise the next year unless there is a natural disaster or epidemic.

10. a. The number of visitors increased in 1999 until 2002 and the number dropped in 2003 and the number of visitors has been increasing since then . I think that there would be an increase in the number of visitors as many visitor attractions has been built in the past year and there is an increasing trend in the number of visitors . There is also almost no epidemic crisis compared to 2003 , which the number of visitors dropped that might have been caused by the SARS .

11. a. Australia: from 1999 to 2003 it slowly increased and decreased again. From 2003 to 2009 the frequency has been increasing. The frequency of visitors in 2009 is higher than the frequency of visitors in 1999.
I think that the number if visitors will most likely continue to increase, provided that there is no financial crisis nor any epidemic or disasters.

12. (a) For each country, describe the variation in the data, starting from 1999 to 2009. Based on the data, would you predict the number of visitors for 2010 is going to be higher or lower than 2009? What makes you think it is higher or lower? [10 marks]

It increased from 1999 to 2001, then dropped from 2001 to 2003.It has been increasing from 2003 to 2009. I think that the number of visitors for 2010 would be higher than 2009 as the graph shows that it has a steady increase since 2003.

13. (a) Australia: It increased from 1999 to 2003 and 2003 to 2009. It decreased from 2003 to 2004. I think in 2010, the number of visitors would be higher than 2009 as from 2004 to 2009, the population has been increasing gradually.

14. I think that it will rise as it has been rising since 1999 except for 2003, unless there is an epidemic.

15. (a) The number of visitors going to Australia increased from 1999 to 2001. It remained constant from 2001 to 2002 before decreasing until 2004. From 2004 to 2008, the number of visitors increased before remaining constant from 2008 to 2009. I think it would increase as the world's economy have recovered since the concession, so people would be willing to spend more to go overseas.
