Simple Plots for Data Inspection

Unit ID: M09-U08 Estimated active time: 25-35 minutes

Use a plot to inspect a defined question, not to decorate the notebook.

axis = module_summary.plot.bar(x="module_id", y="total_minutes", legend=False)
axis.set_title("Total fictional study minutes by module")
axis.set_xlabel("Module")
axis.set_ylabel("Minutes")

Follow the plot with a text table or sentence containing the values needed to understand the pattern. A plot can reveal an unusual value, but it does not explain the cause.

Practice: make the labelled bar chart and add a sentence listing the total for each module. Do not rely on colour alone.
