Introduction to Data Handling

Yesterday, we started the topic by experiencing the 'data collection' process.

There are altogether 4 stages:

What we want to find out:
How many social media accounts does each member in S1-06 have

STAGE 1: Pose the Question
You were asked how many social media accounts you have, however, not allowed to clarify.

Through this activity, we learnt the need to be specific when we gather data. Otherwise, the raw data we collected would not be accurate.


STAGE 2: Collect the data
There are several ways to collect data. Some of them are:

• Online form
• Secondary data (from another source)
• Interview 
• By observation

STAGE 3: Organise and Display Data
Having collected the RAW data: 

we organised them in a FREQUENCY TABLE: 

For DISPLAY, we can use a bar chart, pie chart or a pictogram to present them
You will "receive" an activity that guides you how to use create a frequency table and create charts in Google Sheet.


STAGE 4: Analyse and Interpret the Data

From the table, we can find

• MODE, which is the most frequently occured number
• MODE = 3 (with frequency = 7)

We also learnt there's an OUTLIER, i.e. 24.


NEXT step...
We'll need to figure out how to find the MEAN and MEDIAN when given the frequency table.
