Here are my reflections; Although I can 'guess' what you were investigating, all statistical investigations should start with a question to look at, and a prediction about what you think you'll find out by the end of your survey. You kept your sample sizes equal, even though the small number of BBI students made you limit the sample size- this was not your problem! Well recorded data, but make use of other statistical measures like mean, median, mode and range to interrogate your data before graphing it. Your graph is simple and clear, but would be better if produced using ICT (like Numbers or Excel). There should also be more than one graph in order to help you see trends and patterns- perhaps you could select and compare another group of students from other NZ cities OR zones to see if there is a clearer explanation for the differences you identify.


 * //To use data and statistics/ To use mathematical inquiry// ||
 * Stage 1; Identify the problem and form a question || Interesting question- the question is specific, so finding the appropriate data from the survey should be easy. I'm interested in why you selected this area- do you have an interest in the dreams and aspirations of different ethnic groups? ||
 * Stage 2; Plan and hypothesise || Good sample size, and simple categories to investigate. Your hypothesis is related back to your question, and I like how you have attempted to give a reason for your initial ideas- but it is a bit of an assumption to say Maori and Samoan children have a poor childhood- this may be true in some cases, but 'most' is difficult to prove statistically. ||
 * Stage 3; Data collection || Well collected and sorted into lists- simple to navigate through! ||
 * Stage 4; Analysis of data || I think your table, sorting the groups and their aspirations is a good idea- very clear to read and interpret the data. ||
 * Stage 5; Graphing and charting your data || Good graph- simple to compare the different groups alongside each aspiration. The results are interesting! As a suggestion, it is normally wise to try and graph your data in 2 different ways- what other type of graph do you think would be suitable for this data? ||
 * Stage 6; Interrogating your graphed data || Some good comments about your data- quoting the information from the survey is a good technique. Try to be general too- look for wider patterns and trends- you don't always have to be very specific. ||
 * Stage 7; Conclusion, answer and 'So What' || You have identified the main features in your data- and related them well to your original hypothesis- I'm very interested in the aspirations of the different groups that you have discovered! ||
