Two sections have the same mean but the standard deviation of section 2 is higher than section 1. Which of the two sections is more homogeneous?

Homogeneity is about how similar the scores are within a group. When two groups share the same average, the group with scores that stay closer to that average is more homogeneous. The standard deviation measures how spread out the scores are around the mean: a smaller standard deviation means tighter clustering and more uniform results, while a larger one means more variability. Since section 2 has a higher standard deviation than section 1, its scores are more spread out and less uniform. The section with the tighter clustering around the mean, which is section 1, is therefore more homogeneous.
