I am doing an IB course, the work that I really want you to do for me is called Internal Assessment.We have to pick 2 variables they believe are related to each other in some way and test this using statistical analysis calculations. So IA has to answer on this question : What is the relationship between the amount of time spent using internet and your (high school teenager) amount of sleep? My investigation have to conclude a data, spreadsheets, scatter-graphs and chi-squared test, pearsons product-moment correlation coefficient, regression line etc. There are loads of Internal Assessments on the Internet so you can find them easily if you dont know what IA means. Thank you very much and I am waiting for your help!
