Stephanie+Reflections

Here are the reflections of Stephanie in Y8 Mathex 2009;

Stats Feedback- Aug 09; Outstanding problem to investigate- clear question, and relating to a real context/ issue. The issue also relates well to the Census at School site, and allows you to search through, and to filter data. Next time, like in Science, aim to add your own personal prediction or reason for investigating this issue. The data has been recorded and presented clearly using ICT screenshots from a spreadsheet. Your choice of sample size is sensible and equal across all groups. Your graphs are clear, although somewhat simple. This data would lend itself to some plotting of dot plots, graphing the level of concern for the environment against the time taken in the journey- this would be interesting- do students who live far away care less, because they have no choice? Also, in answer to your problem, indicating the proportion of students who take different means of traffic to school would also help answer a key element of your original question. Good use of statistical measures to look deeper at your results, and to identify any unusual data, and to ensure accuracy. Your analysis coud be clearer, you have attempted to answer the question but haven't really used the awareness measure. Can you think of a way to average out the awareness score for each group- if you can, I'd be interested in seeing the different perceptions between Auckland and Otago students. Main Goal; Make your conclusion relate directly back to your original question.


 * //To use data and statistics/ To use mathematical inquiry// ||
 * Stage 1; Identify the problem and form a question || Clear question- this mentions the data you'll be interested in finding out from the survey. How did you come across this idea? Is it something you're interested in? Give a little explanation about your reasons for investigating this area. ||
 * Stage 2; Plan and hypothesise || Reasonable sample sizes- I appreciate that your analysis would take a long time to do- but with a survey of 17,000 people, you could have gone a bit bigger? Your hypothesis is clear, with good justification for your thinking. Well planned and organised in your presentation. ||
 * Stage 3; Data collection || Well done for organising the tables of data to support your graphs. The only other analysis you could have done is maybe looking at the distances from the original country of the desired countries to visit- this could have given some indication of how far people wanted to travel, but would have been very tricky! ||
 * Stage 4; Analysis of data || The only other analysis you could have done is maybe looking at the distances from the original country of the desired countries to visit- this could have given some indication of how far people wanted to travel, but would have been very tricky! ||
 * Stage 5; Graphing and charting your data || Clear and informative- pie charts were the best choice for this 'proportion' data. The only other graph that would have been appropriate would have been spider web charts (see Lloyd's presentation). ||
 * Stage 6; Interrogating your graphed data || I can't find any evidence of your reflections on the graphs you created- what did they show? How did they support the hypothesis you made? ||
 * Stage 7; Conclusion, answer and 'So What' || What does your data tell us? How can we use it with BBI students- you need to do some thinking about the results you came up with. ||
