Extracts from this document. 1st of February 2006 GCSE Mathematics Coursework- Data Handling Hypothesis: Children between Year 7-11 change physically and mentally as they mature. Aims: To investigate my hypothesis I have set some aims: * To investigate the height change between year groups * To observe correlation between IQ and age * To investigate changes in favourite TV genre choice Introduction: I have chosen to investigate this hypothesis for my coursework because I think it will be interesting and lead to many fascinating questions and hopefully answers. Method: To investigate my aims I intend to take a sample of the data. I will take a stratified sample of the data taking a proportion of boys and girls from every year group. To take a stratified sample I will divide the whole population of children into year group and gender e.g. Year 7 Boys. I will then take 10% of each stratum to gain fair representation of each stratum. Having taken this sample I will attempt to answer aim 1. I will group together the height data within the stratum creating a frequency table. From this, I will plot a cumulative frequency graph. After this, I will find the median, the upper and lower quartiles and create a box and whisker plot. I will do this to each strata, place all 5 box and whisker diagrams on the same page and compare them. I will use box and whisker diagrams as they should be able to see the jump in heights between the year groups clearly. I will also be able to asses the skew of the data. I will do this for boys and girls separately as they have their growth spurts at different times. I will take that standard deviation of the children's heights as this will allow me to see how far spread the children's heights are in relation to the mean average. From this information, I should be able to infer a judgment on some of the physical changes of children between these.
Internally-assessed mark submission is changing from Summer 2016 We launched the pilot of our new e-Submissions (e-Subs) system to submit marks in the autumn term and trialled it for the November 2015 exams series. We are pleased to say that the pilot of e-Subs went exceedingly well. The great thing about e-Subs is that as a teacher you can submit marks yourself, you just need an e-AQA login and the required access provided by your Exams Officer.We're confident that our online system, will offer schools and colleges a more efficient way to submit coursework/controlled assessment marks or grades and save you time.If you are submitting marks for your students in the November re-sit series, we encourage you to check with your exams officer that you have an e-AQA user name and password or register. Once the system is live for the November series, your exams officer can give you access to e-Subs, so you are ready to input marks straight away.We've published e-Learning modules on our website, so you can preview what the system will look like and be comfortable and familiar with the system ready for the November series. For further questions about e-Subs, call our Customer Services team on 0800 197 7162 (or +44 203 671 8010 from outside the UK) or email eos@aqa.org.ukTeacher Online StandardisationOur Teacher Online Standardisation (T-OLS) system allows teachers and departments to work through exemplar and standardisation material quickly and easily.Access for all teachersWith online standardisation, all teachers can go online to see the marking advice from the Principal Moderator at a time that suits them.Access for all schoolsAll schools taking AQA specifications in these subjects can participate.Examples of work marked by the Principal ModeratorSee pieces of candidate work marked by the Principal Moderator plus additional guidance.
