In ANOVA, error variability is also known as within-group variation. It measures the variation of the response variable within each group or treatment. The other options - total variation and between-groups variation - refer to the overall variability of the response variable and the variation between different groups or treatments, respectively. However, SSE specifically refers to the variation within each group, making choice B the correct answer.
