It is impossible to estimate regression coefficients before doing the research and data collection study so power studies aren’t really relevant here. Instead, just ensure that the number of data points (i.e. observations or cases) is considerably more than – 5 to 10 times – the number of variables. (A reference for this rule of thumb is: Kleinbaum, Kupper and Muller (1988).)

Big Ideas/Guiding Questions. This unit focuses on collecting, organising, displaying and analysing data. The students will be introduced to histograms, divided bar graphs and sector graphs as other ways of displaying data. The ability to select an appropriate graph to represent data and be aware of misleading graphs will be addressed. The analysis of data will involve the . calculation of mean ...

In an era of Big data this change of paradigm for data collection presents the possibility to collect and integrate many types of data from many different sources. Combining data sources to produce new information is an additional interesting challenge in the near future. Combining “traditional” data sources, such as surveys and administrative data, with new data sources as well as new ...
