Practice Questions (compulsory)

Dear all,
As Mr Chua has rightly pointed out, learning should be an on-going process and should not be just for the sake of tests or examination. One of SST's goals is to develop 'life-long learners' hence it is imperative to begin with the right mindset and attitude. I have identified the following questions from the chapters covered in Term 2 for compulsory practice.

Please detached the questions or copy the questions from the workbook for easy personal reference later on. Complete working to be shown and please use foolscap papers.

STATISTICS (ANALYSIS) : mean, mode & median

The Next Phase in Statistics is Data Analysis. In this segment we will be focusing on the following:

.1 Averages

.2 Histogram

.3 Other forms of presentation (Dot Diagram, Stem and Leaf)

Follow through the following series of tasks

----------------------------------------------------------------------------------------------------------

.1 Averages

'Before you can begin to understand statistics, there are four terms you will need to fully understand. The first term 'average' is something we have been familiar with from a

very early age when we start analyzing our marks on report cards. We add together all of our test results and then divide it by the sum of the total number of marks there are. We often call it the average. However, statistically it's the Mean!' [source: http://math.about.com]

Your task:

1. Define the following statistical terms: Mean, Mode and Median
2. You may refer to the following link for assistance [click here]
3. Provide an example on each of the terms
4. When do we use mean, mode or median?

----------------------------------------------------------------------------------------------------------

.2 Frequency Table and Histogram

What is/are the primary difference/s between Histogram and Bar Chart?

Your Task

Do a simple survey in class and complete the following tasks
