Watch the following examples. Each comes with a question and the explanation on how to solve the problem.
1. Pause the question. Read the diagram carefully and think what formula would help you to solve for the unknown.
2. Think how you would solve the problem - you may need to write down an equation in order to solve for the unknown.
3. Next, continue to watch the clip and listen to the explanation. Is this similar to what you have thought of? Look out for the presentation of the working.

Data Handling: Is the Graph creating a true first impression?


Look at this graph... something is not quite right... what's wrong?

Let's Ponder (Discussion 1): Is it true that...

In preparation of the I&E Bazaar, class S1-10 conducted a survey and found that the McDonald's "Crispy Chicken Breakfast Deluxe" meal is very popular amongst the SST students. They decided to sell a similar breakfast set in that morning. 

To advertise their stall, they included the following chart in their promotional flyer. 
Their publicity gimmick was, "We are one-third of what you normally paid!"



From a consumer's point of view, what is your reaction to this publicity stunt?
Hint: Remember to elaborate your response by applying what we learnt in this topic

Remember to include your Group number before submitting the comment.

Let's Ponder (Discussion 2): Is the Change really Significant?

In the annual Town Council report, it reported the effort put in to improve the environment of the residents in the area it was in-charge of.

One aspect is the collection of refuse, which was a feedback by the residents.
The diagram shows the reported non-collections of refuse as a percentage of the total number of households in a town


Study the above diagram carefully.

1. Do you agree that the Town Council has made significant improvement? Why?

2. With reference to the visual representation, point out at least 2 areas that need improvement.
- Why do you think these 2 areas require improvement
- Suggest how to improve the representation.

Remember to include your Group number before submitting the comment.

Let's Ponder (Discussion 3): It's a "Fair" Representation?

The diagram represents the sales of socks at the bookshop in the months of April and May. In April, she sold 10 pairs of socks.

To report the improved sales to the company, the bookshop auntie represented decided to represent the sales using a 'pictogram'.



Does the above "pictogram" give a fair representation of the socks sold in these 2 months?
Give a reason to your answer.

What would you suggest to the bookshop owner to present the sales in an 'objective' manner?

Remember to include your Group number before submitting the comment.

Knowing Singapore through Data

In unit 10.3 (Representation and Interpretation of Data), we looked at how various organisations are presenting data for different groups of audience.

Here are the resources we visited:

1. NEA website
We discussed how this information is useful to us, layman




2. Department of Singapore Statistics
We learn more about Singapore through data presented in charts, making it more appealing and easier to understand.
  • Statistics: Population Trends
    • Section: Aging Population [animated presentations]
      • Scroll down to view the animated Resident Population Pyramid to see how the trend looks like over time.


3. Singapore's Open Data portal: Data.gov.sg

[5 August 2016] Data Handling: An Introduction

In this lesson, using the data contributed by the individuals in the class...

1. We created a Frequency Table where the number of occurrences of each number given is clearly indicated.

2. In total, there are 22 data points.

3. A Histogram is also created, based on the data points and frequency captured in the frequency table.

4. We learnt the term, outlier, which is an observation point that is distant from other observations. In this case, we have two outliers, with 35 doors being the most extreme case.


We also learnt the following (through the above scenario)

1. Mean: The sum of all data points divided by the total number of data points
In this case, Mean = 9 21/22 doors or 9.95 doors (to 3 significant figures)


2. Mode: The most frequently occured data point
In this case, Mode = 7 doors
This can be identified directly from the histogram.


3. Median: The middle value
Since there are 22 data points, the middle value would be the mean of the value at the 11th and 12th position.
Value at the 11th position = 8 doors
Value at the 12th position = 8 doors
Hence, median = (8 + 8)/ 2 = 8 doors

Note: Before obtaining the median, the data points must be arranged in either ascending or descending order.
