Problem
We want to find out if the number of hours students work on a TMA can predict their marks. To investigate this research question, we collect data on how long students worked on a TMA and what mark they achieved. We use Simple Linear Regression to build a regression model and analyse the data.
Our results show that the average student worked for 12 hours on their TMA and that students achieved, on average, 68.87% as a mark. We also know that the intercept of our model is 52.65 and the slope 5.87. What would our regression equation for this data look like?
