        # Statistics lab
        This numerical lab consists a few small tasks, which cover the key statistics topics that were introduced in the previous chapter.
        They are also preparatory for the following labs, where you would have to use the same concepts in more complicated situations.
        In particular, if you are using python, it would be beneficial to solve some of this exercises by creating specific functions that can the be reused (maybe with small modifications) in the following labs.

        ## Tasks
        1. Average and standard error
        2. Propagation of uncertainty
        3. Comparison of averages
        4. Linear Fit
        5. Non linear fit
        6. Outlier detection


        ## Instructions
        1. Type your student ID
        2. Select a task
        3. Click "Run Experiment"
        4. Analysed the data
