A sports science study investigates the impact of two different warm-up protocols on the dynamic balance of gymnasts. Dynamic balance is assessed using a standardised balance index, where scores range from 0 to 100 (a higher score indicates superior balance control). The lowest score recorded in the study was 22 and the highest score was 95.

Table 1: Mean balance scores for Protocol A and Protocol B

	Protocol A (Active dynamic stretching)	Protocol B (Static stretching)
Mean balance score	78.4	61.2

In this study, the balance scores are initially treated as interval data.
