Here are my reflections;

Good start- a question at the beginning of an investigation always gives your work direction, and helps when it comes to concluding or answering at the end. Clear collection of data, and good range of year groups too. I like the way you recorded in a table AND how the data was grouped- a pity you didn't attempt to calculate the avearages for each 'group' of the classification- you could have also recorded the average 'score' for each year group to see which was the most enviro-aware group. Clear graphs, representing two views of your data help to show any trends and patterns. Your conclusions are accurate and show a good understanding of the graphed information. Next step would be to try and repeat this study, focusing on the different results you could get for students in different regions of NZ.


 * //To use data and statistics/ To use mathematical inquiry// ||
 * Stage 1; Identify the problem and form a question || Clear question- good for coming back to in your conclusion, and for keeping your investigation focused on the key issues. A good tip is to explain why you've selected this question- why it matters to you, and why it's worth investigating. ||
 * Stage 2; Plan and hypothesise || Well explained with some mention of the reason why this is your idea. 100 students is a reasonable amount, but you could have gone for more students because you had 17,000 to select from, and you were only really looking for 2 main bits of info. ||
 * Stage 3; Data collection || Good use of the census- you focused on your 2 main questions without getting involved in other issues. ||
 * Stage 4; Analysis of data || Well recorded- seeing the data as lists, grouped in order is a good idea. Take the time to describe the patterns or trends when the data is in this stage. ||
 * Stage 5; Graphing and charting your data || Interesting graph- there is certainly a clear link in your data BUT your interrogation needs to be thought about carefully... ||
 * Stage 6; Interrogating your graphed data || You have identified the fact that there is a link- this link (using your data) is only that the same number of people are very, mildly, or not at all concerned for the environment and for recycling. Please be aware- these may NOT be the SAME people who are aware/ not aware so you can't say there is a link!! ||
 * Stage 7; Conclusion, answer and 'So What' || Look more closely- you may need to find the individual details of the people and see (one person at a time) if people had equal concern for the 2 enviro issues. ||
