1. The problem asks to identify the outlier in the dataset $6, 4, 7, 9, 23, 5, 10$. 2. An outlier is a value that is significantly different from the other values in the dataset. 3. Looking at the numbers, most values are between 4 and 10, but $23$ is much larger than the rest. 4. Therefore, the outlier in the dataset is $23$. 5. For the second problem, we need to describe the dataset $7, 2, 9, 6, 2, 8, 3, 6, 4$ in terms of modality. 6. Modality refers to the number of modes (most frequent values) in a dataset. 7. The values $2$ and $6$ both appear twice, making the dataset bimodal (two modes). 8. Hence, the correct description is bimodal. Final answers: - Outlier: $23$ - Dataset description: Bimodal
