This lesson describes the data analysis essential for IB physics Paper 1B and the Internal Assessment. It has 2 sections: The first covers random & systematic errors, error estimation & propagation. This includes the standard formulae used by IB for functions with sums & differences, products & division, and powers. It also describes how to deal with more complex functions such as the trigonometric operators. The second deals with straight line fitting and how to extract error estimates from th
