An aerospace engineer is testing the flight duration (in hours) of two new drone battery designs, Design P and Design Q, under continuous high-load operations.

Table 1: Mean flight duration (in hours) and standard deviations for both battery designs

	Design P	Design Q
Mean	5.42	4.85
Standard deviation	0.21	0.94

The engineer originally planned to use the range to measure the dispersion of flight durations for each battery design. However, during testing, one battery of Design P experienced a thermal-throttling event, resulting in an exceptionally short flight duration.

Explain how using the standard deviation rather than the range in this situation would improve the quality of the statistical analysis.
