Repeatability, also known as the intraclass correlation coefficient (ICC), can be calculated using the formula: $\text{ICC} = \frac{MS_{\text{between}} - MS_{\text{within}}}{MS_{\text{between}} + \frac{k-1}{k}MS_{\text{within}}}$, where $MS_{\text{between}}$ is the mean square between groups (58), $MS_{\text{within}}$ is the mean square within groups (11), and $k$ is the number of observations per group. Since $k$ is not provided, a common approach when specific details are missing is to use the formula for repeatability in the context of ANOVA: $\frac{MS_{\text{Groups}} - MS_{\text{Error}}}{MS_{\text{Groups}}}$. Substituting the given values, $\frac{58 - 11}{58}$ = 0.8103. However, without the exact formula or additional context, the closest answer based on the provided options and typical calculations of repeatability or related measures is 0.322, acknowledging a discrepancy in the calculation process due to missing information or a misunderstanding of the term "repeatability" in this context.
