IB Physics HL S2.2.1 Collecting data
Practise collecting enough measurements over a useful range, so later averages, graphs, and uncertainty judgments are well supported.
How this is tested
- explain why one reading per setting is weak, and why repeats are needed to reduce uncertainty in the data table
- choose values of the independent variable across a wide range so the graph can show the trend clearly
