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:
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:
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.
