Examine extreme data points: check Wire 4 ($R = 0.068$) which has the highest length (2.0 m) and smallest area (0.5 mm²).
Resistance formula is $R = \rho L / A$. Increasing length $L$ directly increases resistance, while decreasing cross-sectional area $A$ inversely increases resistance. Wire 4 (longest length 2.0 m and smallest area 0.5 mm²) exhibited the hig...
