The data set below indicates a researcher's motivation level (scored out of 10) towards their research project over time. Time, t, is measured in years since their thesis start date.
- Download and save the data set to your computer, then import it into MATLAB
- Use the scatter function in MATLAB to plot the data
- Fit a polynomial model to the data using the fit or polyfit functions in MATLAB. Hint: you may need to try different degrees (quadratic, cubic...)
- Plot your fitted model on your scatterplot
- Use the LaTeX interpreter to change the plot title to be Motivation as a function of time (t), using your fitted model
- Export your MATLAB code and plot into LaTeX
- Open the .tex file and add a title, then compile it into a .pdf
