This set of lessons teaches you how to manipulate data, plot it, analyse it and draw conclusions from it. Two software packages are used: Excel (or another spreadsheet such as iWork Numbers), and Python (with the numerical python and matplotlib packages). Some tasks can be done in either, while some require the greater power of Python. Reference Guide for Python Data Handling . Back to Main Lab Skills Page .
