3. Learning analytics is a type of data analytics that involves the measurement, analysis and reporting of data about learners and their contexts. It is intended to help understand and optimise learning and the environments in which it occurs. You are interested in exploring how students' study motivation will be affected by the use of LMS dashboards to display their performance relative to others. Identify a research question and hypothesis for a research study you might undertake to investigate one aspect of this issue. Label the independent variable and the dependent variable in your hypothesis.
