Here are my reflections; You shoiuld always start your investigations in Maths with a question- this helps you to form a hypothesis AND also helps you to form your conclusion as you reflect on your data. You have picked a good sample size, and recorded your data clearly, but you could have also calculated the stastistical averages of how fit people thought they were, and compared these measures to give you more data. Your graphs are simple and well constructed- clearly labelled, BUT the line graph is inaccurate and not appropriate for discrete data like numbers of people because there could never be 11.5 students aged 12 years old- these graphs should only be used for continuous data like temperature or height. Your conclusion is very short- partly because you didn't have a prediction or question to answer. I would like you to challenge yourself to look for more patterns in the data, such as students in Auckland compared to Canterbury etc.


 * //To use data and statistics/ To use mathematical inquiry// ||
 * Stage 1; Identify the problem and form a question || Clear question but you need to explain why you have selected this as an issue and what you can learn/ change by finding out any trends or patterns in the data. ||
 * Stage 2; Plan and hypothesise || Add more details to your hypothesis- it is very important to explain why you feel this way. Your plan is clear, and your sample size is OK- remember; bigger is better to ensure the data/ trend is accurate. ||
 * Stage 3; Data collection || Well grouped and sorted. ||
 * Stage 4; Analysis of data || Good use of statistical measure of average to compare the groups- remember to use the other measures of average too- median and mode would be appropriate for this type of data. ||
 * Stage 5; Graphing and charting your data || Your bar chart is a good start- it is well labelled, but you would need to graph your averages to answer your question more accurately. It is generally a good idea to create more than one graph to illustrate patterns and trends in your data. ||
 * Stage 6; Interrogating your graphed data || Brief- you need to look more closely at your statistics and for other trends and comparisons in your data in order to prove or disprove your idea. ||
 * Stage 7; Conclusion, answer and 'So What' || No conclusion seen- refer back to your original question and your hypothesis for your conclusion. What is your 'So What' from this investigation? Now you've seen this pattern, what can we do with this info? ||
