Uncovering the stories

Read below or download as a MS Word document.

The population consists of over 21000 South Australian, Western Australain and Northern Territory (mainly South Australian) actual school students from Years 8 - Adult re-entry. These students completed an online survey (during March 2003) consisting of 34 student designed questions. While this group could be considered as a sample of all South Australian students (Years 8 - Adult re-entry) studying in South Australian schools, for learning purposes we ask you to consider them as a population.

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 a sample of the responses and analyse it, ultimately estimating parameters from which the stories can flow.

Our 'sampler' will allow you to select a SRS of the responses of upto 255 individuals from our population.

One part of a statisticians life is to design and implement appropriate sampling techniques to gather data from a sample of a popualtion 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:

In this rare situation, it is possible to find out whether or not your analysis and subsequesnt 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 doing this until later in 2003, so for now you will just have to dream up a question of interest, sample, analyse, conject and statistically prove.

We hope you enjoy this rare opportunity to work with real data that you (SA, WA and NT students) contributed to. So that we can reveal the truth about the sorts of things you chose to investigate, please submit the details of your investigation to us and we will keep a record of it and reveal the truth late in 2003. We also invite you to submit your work to be considered for publishing on this site.

Some examples of possible questions are:

The possibilities are large in number.

Please remember though that any of your conclusions are about the responses from the 21000 plus 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.
