A neuroergonomics researcher investigates whether exposure to diffused lavender essential oil enhances fine motor control and reduces error rates during a high-precision micro-assembly task. In a controlled laboratory experiment, participants in the experimental group perform the assembly task in a room diffused with lavender oil, while a control group performs the task in an identical room with no scent. The researcher measures performance exclusively using quantitative variables: the time taken to complete the assembly in seconds and the total number of microscopic positioning errors recorded by an automated tracking sensor.
Outline one strength and one weakness of not having any qualitative data in this study.
