IB Physics SL S1.3.5 Graphing
Practise plotting and interpreting graphs, drawing best-fit lines or curves, using error bars, and extracting gradients or intercepts from data.
How this is tested
- draw a single best-fit line or curve that follows the trend and respects the plotted error bars
- determine a gradient using two well-spaced points on the best-fit line, not raw data points
- use extrapolation or a maximum-gradient line to estimate an intercept or an uncertainty from the graph
