- Use the mean when the data is symmetric and has no outliers. Use the median when the data is skewed or has outliers, as it is less affected by extreme values.
- True
- Median, because the value 105 is a significant outlier that would skew the mean.
- Mode
- Mode, because the data is categorical (names of pets), not numerical.
- Mean, because the data is numerical and there are no extreme outliers that would significantly distort the average.
- False
- Median
- [This requires collecting real data from classmates. The answer depends on the specific numbers collected.]
- [This depends on the data collected in question 9. Generally, for sibling count data which can have outliers (e.g., one student with many siblings), the median is often more appropriate.]
