Practice question · Sort into groups
Sort each element into its role in graphical analysis.
Groups: Graph component · Fit quality metric
- Title
- Residual plot
- (coefficient of determination)
- Axis labels with units
- Chi-squared per degree of freedom
- Error bars
Hints
- Separate what a graph must show from how a fit is judged.
- Numerical fit measures are not presentation elements.
Show the answer
Graph component: Axis labels with units, Error bars, Title
Fit quality metric: (coefficient of determination), Residual plot, Chi-squared per degree of freedom
Why
Graphs need labels, titles, and error bars; fit quality is judged by , residuals, and χ².
