Data Handling

1) The line graph is the inappropriate one.
2)The line graph is supposed to show the change in the numbers and it is not appropriate to use it for weather.

Data Handling: Choice of Graphs by Joel Tan

Can you identify the one that is not appropriate?
Answer: Yes, It is the line graph

Why do you think it's not appropriate?
Answer: A line graph is only for 2 variable, 1 at the y axis and 1 at the x axis. Many variables in the x axis can get people confused.

What makes you think the 3 remaining graphs are appropriate? 
Answer: Other x axis can have 1 or more variable.

1)This line graph is inappropriate
2)The line graph is suppose to show changes over a time of period.
3)The remaining 3 is correct

Data Handling (Pasan Hettige)

1)The line graph shown is inappropriate.
2)It is used to show a change in a period of time
3)The other three ar correct

Data Handling: Choice of Graphs by Javier Ng



1) Can you identify the one that is not appropriate?

The line graph on the left/shown is not appropriate.

2) Why do you think it's not appropriate?

A line graph is to show something changing over a period of time but the information given is at that time and not over a period of time.


3) What makes you think the 3 remaining graphs are appropriate?

The 3 remaining graphs show the 
information at that time and not over a period of time.

Data Handling ( Ryan Hong )

The line graph shown is inappropriate.
It is only used to show the change in the period of time.
The three other graphs shown were correct in showing the information.

Data Handling: Choice of Graphs by Yue Sheng

  1)The line graph is the inappropriate one.
2)Line graph are meant for observing changes,and  not suited for weather as it is impossible to connect the weather with a line graph.
3)The other graphs show how much of the world is experiencing their specific kind of weather which is appropriate in this context.

Data Handling: Choice of Graphs by Mahidhar Reddy

1) The line graph is the inappropriate one.
2)The line graph is supposed to show the change in the numbers and it is not appropriate to use it for weather.
3)The other three graphs perfectly depicts the weather.

Choice of graphs:Darryl Chan

Can you identify the one that is not appropriate?
 The line graph is incorrect

Why do you think it's not appropriate? Line graph is only used when it is over time the graph would be appropriate if it was the bar graph

What makes you think the 3 remaining graphs are appropriate?
The three remaining graph are correct because it shows how many countries are having such weather

Data Handling: Choice of Graphs by Wynn

Question:  Can you identify the one that is not appropriate?
 Answer: The line graph is not correct.
Question:  Why do you think it's not appropriate?
Answer: A line graph is to show a change over a period of time.
Question:  What makes you think the 3 remaining graphs are appropriate?
Answer: It is used too represent a change.

Data Handling: Choice of Graphs by Xavier Toh

1) The line graph is inappropriate.
2) Line graphs are used to know the amount of change of something instead of  how much there is of something.
3)The three other graphs show the same number of symbols like the sun as depicted on the weather map. For example, the weathers are all sunny, so the pie chart is filled with yellow, the colour representing the sun.

Data Handling: Choice of Graphs by Maximilian Oh

1) The inappropriate one is the line graph
2) Line graphs are used to see the change in numbers of something and not how much there is of the weather.
3)The three other graphs show exactly how much of the world has that kind of weather.

Data Handling: Choice of Graphs by Christian Zheng Hao

Q: Can you identify the one that is not appropriate?
A: The pie charts.
Q: Why do you think it's not appropriate?
A: It is very confusing for a person to understand the information.
Q: What makes you think the 3 remaining graphs are appropriate?
A: The remaining 3 graphs are able to deliver the information easier.



Data Handling: Choice of Graphs by Bryan Ho

Q: Can you identify the one that is not appropriate?
A: The line graph.
Q: Why do you think it's not appropriate?
A: A line graph is not suitable for weather statistics and it very confusing.
Q: What makes you think the 3 remaining graphs are appropriate?
A: They are more clearcut and easier to differentiate.
         

Data Handling: Interactive activity

Q: Can you identify the one that is not appropriate?

A: Yes, it is the line graph.
--------------------------------------------------------
Q: Why do you think it's not appropriate?
---------------------------------------------------------
A: The line graph is not neatly aligned unlike the other graphs, so it seems unsuitable to handle this type of classification (weather).
-------------------------------------------------------
Q:What makes you think the 3 remaining graphs are appropriate?
-------------------------------------------------------
A: They seem a lot easier to understand than the line graph and appear to be more flexible when their statistics are changed
Screenshot of line graph.

Data Handling by Keagan Wong

The inappropriate graph is the line graph.
I think it is not appropriate as the weathers are not connected and is completely at the same time but a different place. If they use a line graph they are saying that the weathers are a certain amount of sun, a certain amount of rain ext.
The remaining three graphs are appropriate in my opinion is because they are separated and we can tell it is not one after another.

Data Handling: Choice of Graphs by Cornelius Lee

                                                                              Can you identify the one that is not appropriate?
Answer: Yes.It is the line graph.

Why?
Answer: It is not appropriate as a line graph does not do this type of statistics.

What makes you think the 3 remaining graphs are appropriate?
Answer: They look more easy to understand than the line graph.

What's up in the March Vacation?

Dear S1-02

There are several things to accomplish in the March Vacation, and you will find most of the stuff in the GoogleSite > Mathematics site

(1) Performance Task - Viva Voce 
  • This is going to constitute to 5% of your overall Summative Assessment results.
  • Refer to GoogleSite > Mathematics site > Performance Tasks (left panel).
  • This is similar to the Viva Voce Practice that we did.
  • You may go through the questions and attempt your choice question on paper first.
  • Try to do the recording after Monday, when I would be able to provide you feedback to your practice so that you can avoid what you should not do.
  • Note the deadline of the task.
(2) Vacation Engagement
You will be learning a sub-topic on your own during the March Vacation - Introduction to Data Handling.
  • Refer to  GoogleSite > Mathematics site > Vacation Engagement
  • It is a revisit of the what you learnt in primary school.
  • You will be using resources mostly from the AceLearning and attempting exercises at the Maths Blog or GoogleForm.
  • There is a set of homework questions from the Maths Workbook.
  • Note the deadline of the task.
(3) Common Test in Term 2 Week 6
The topics are already listed in the GoogleSite, to give you an early head-start (preparation).
You may do the following as practice: 
  • Workbook 1: Revision Test B1
    • Omit Q5, Q6, Q7
  • Workbook 1: Revision Test B2
    • Omit Q2, Q5, Q6, Q7, Q8

Those who are suppose to attend the support programme, please turn up punctually with the materials required (see the earlier post).
For those who are not identified to attend the support programme but would like to turn up at the scheduled time as well.

(5) Consultation during March Vacation
The various consultation channels remain open during the March Vacation:
  • Email
  • Online Chat

Level Test 1 - Test Solution Q7

Dear S1-02

Some of you gave feedback that the "Explanation in words" for Q7 is not clearly scanned.
Here's the responses:

(a) The order of operation is incorrect. When there is only x (multiplication) and ÷ (division) on the same line, we should work from left to right.

(b) -3^2 should be -9 as we are only squaring "3".
Square root of (16/25) should be 4/5. The square root applies to both numbers on the numerator and denominator.
Recall that: The set of solution is available in the GoogleSite.
