Good start- you explained clearly what you would like to find out in your survey, and what you intended to do to find out. This is a good idea- it could be improved more by adding your own prediction about what you think your results will show. Good sample sizes- you have picked some interesting varaibals which may have an effect on the pulse. Your graphs are mainly bar charts- your data would lend itself to a dot plot (or more than one) with ages plotted against another axis of pulse rate. Different colour dots could indicate gender and location of the surveyed student. It would make spotting any patterns and trends easier- and also the ability to notice any changes over time would also become clearer. Your analysis and use of data has allowed you to make clear statements in your conclusions as well as using your graphs- tip; graph some of the averages too, to make them clearer to see and understand. Your results are interesting (and a bit worrying too- for any student approaching Y11 in a few years time!!

Q- Does the length of people's right foot affect their height? Is this different in boys and girls? ||
 * //To use data and statistics/ To use mathematical inquiry// ||
 * Stage 1; Identify the problem and form a question || Well formed question will provide your inquiry with good direction- there is also a subsiduary question which will allow you to get more interesting evidence.
 * Stage 2; Plan and hypothesise || You have addressed both parts of the question in your hypothesis- a good idea is to try and give reasons for your thoughts in any prediction- are they based on experience or just guesses? ||
 * Stage 3; Data collection || Well planned- good sample size and restrictions should make your data accurate- eliminating other possible variables and factors is a great thought. ||
 * Stage 4; Analysis of data || Identifying and eliminating 'rogue' data that may be caused by typing errors is a good place to start- this would influence and skew your data, so best to eliminate it before you graph. Good use of colour coding to help your sorting. ||
 * Stage 5; Graphing and charting your data || Well constructed by hand- good labelling and accurately drawn- the correct type of graph to use for this purpose. Your trend line was accurately plotted and it does show a very slight trend in the results. ||
 * Stage 6; Interrogating your graphed data || Your trend line is a form of looking more closely and interrogating your graph- well done. You looked at the trend line and drew a good example- plotting from the line itself to the axes in order to prove your point- and you also picked out how the trend lines were diverging- this was an interesting extra point. ||
 * Stage 7; Conclusion, answer and 'So What' || Good look back to your hypothesis, and you also added extra points to it, attempting to explain the reasons for the events. What would now be your 'So What' now that you are the owner of such interesting information? How do you intend to use this new knowledge??! Good investigation! ||
