This study unit aims to develop the skills for handling simple calculations in science involving the application of basic statistics to experimental data. This is achieved by references given to sections and pages in the study text, Essential Mathematics and Statistics for Science, and associated QVA tutorials - questions with video worked answers.
NB: The video tips and QVAs appear in 'pop-up' windows. If your browser blocks 'pop-ups', you can use CTRL+Enter or Right click with the mouse.
