Pairwise comparison of the R2 values for the two selected pairs of key dimension candidates indicated that the pair HL and HC is preferred as glove key dimensions. As illustrated in Table 4, the R2 values of each hand dimension in relation to the pairs of key dimension candidates were compared to identify which key dimension candidate pair better explains the variation of the hand dimension. Of the 67 hand dimensions (excluding the key dimension candidates), a slightly larger percentage (57% for males and 64% for females) of the regression equations of the pair HL and HC showed a higher R2.
