Read my reflections on Mathex 2009;


 * //To use data and statistics/ To use mathematical inquiry// ||
 * Stage 1; Identify the problem and form a question || Interesting and relevant to your age and peer group. Don't forget to explain the reason behind the choice of this issue- this will also connect to your 'So What' when you have identified the patterns and trends you may be thinking will appear. ||
 * Stage 2; Plan and hypothesise || Your hypothesis is clear- and you have connected it to a reason why. Your plan is clear- and your sample size is appropriate (but could be extended to include other year groups to see if people's bag carrying habits change with age!) You have been VERY precise in the questions you'll be looking at to collect your data. ||
 * Stage 3; Data collection || Well listed- sorting them into size (of bag) order may have revealed early trends around your issue. ||
 * Stage 4; Analysis of data || Not alot of analysis- straight into graphing. ||
 * Stage 5; Graphing and charting your data || Your pie chart is well constructed BUT only proves how people carry their bags. The graph has no connection to their bag sizes- for this you'd have to produce a pie chart for the students with bags between certain weights in order to make a comparison. ||
 * Stage 6; Interrogating your graphed data || Very brief and NOT looking at the REAL connections you needed in order to answer the question you are attempting to order. You have identified preferred carrying methods but have made no attempt to link this to the weight of the bags. A type of dot plot would also suffice for this task. ||
 * Stage 7; Conclusion, answer and 'So What' || You have concluded about the preferred methods BUT you need to go back and do some analysis of weight too in order to truly answer your question. ||
