While
the many thousands of students who completed the online survey (during 2004)
consisting of 40 student designed
questions could be considered as a sample of all Australian students (Years
7 - Adult re-entry) studying in Australian schools, **for learning purposes
we ask you to consider them as a population.**

It should be noted that if considered as a sample, the sample is not likely to be representative.

The
database of responses from the population is **intriguing**, it holds many
**interesting stories** that you would love to know and maybe write about
in your student newspaper, talk about on your student radio or at school assemblies.

**As
is often the case in real life**, you are **not** going to be able to
view all the data from the population and uncover the stories with 100% certainity,
but you will be able to take random samples of the responses and analyse them,
ultimately estimating parameters from which the stories can flow.

Our
**'sampler'** will allow you to select a **SRS** of the responses of
up to 255 individuals from the **population**. This will be delivered to
you as a CSV file that will open in Microsoft Excel or can be imported into
other applications. Each column of data has a heading that relates to one
of the questions in the survey. The document columntitles(2004).pdf
explains the headings.

One
part of a statistician's life is to design and implement appropriate sampling
techniques to gather data from a **sample** of a population of interest
in order to analyse it and **estimate** **parameters** associated with
the population. One example of this is the TV
ratings process.

**It
is now up to you to decide what stories you want to unearth**.

Read through the questions and decide what facets of the information gathered is of interest to you and then do the following:

- Clearly state the question of interest to you
- Decide upon the characteristics of the sample you require data from.
- Go to the sampler and selected an appropriate sample for your purposes
- Analyse your sample data in an appropriate manner
- From the results of your analysis, make appropriate conjectures
- If you have the skills to do so, attempt to prove (statistically) your conjecture(s)

In
this rare situation, it is possible to find out whether or not your analysis
and subsequent attempts at statisitcal proof reflect what is the actual case
- **as The Baker Centre can tap into the population and look!** But we
won't be publishing much of the 'actual case' information on the web. You
can email us though and seek the truth - we may tell you.

We
hope you enjoy this **rare opportunity** to work with real data that you
contributed to.

Some examples of possible questions are:

- What is the proportion of girls in the population?
- What is the proportion of public school students in the population?
- What was the mean amount of money earned 'last week' by the students in the population?
- Are girls more likely than boys to have there behaviour and opinions influenced by peers?
- Do Year 8 girls spend more time playing computer games than Year 8boys?
- Students of which year level of are most in favour of homework?

The possibilities are large in number - be creative.

**Please
remember though that any of your conclusions are about the responses from
the many thousands of students who took part in the survey. Your findings
may or may not reflect the actual case in our society, this you can not be
sure - why? You think about it.**

Enjoy!
