Transcribed Image Text:**Relationship Between Age and Vocabulary Size**
Is there a relationship between the age of children and the number of words in their vocabulary? The ages (in years) and the number of words in their vocabulary provide the following data:
| Age, x | 1 | 2 | 3 | 4 | 5 | 6 | 3 | 5 | 2 | 4 | 6 |
|--------|-----|-----|-----|------|------|------|-----|------|-----|------|------|
| Number of Words, y | 15 | 220 | 540 | 1100 | 2100 | 2600 | 730 | 2200 | 490 | 1000 | 2400 |
This table shows that as the age of children increases, the number of words they know tends to increase, suggesting a potential relationship between age and vocabulary growth. Further analysis can be done to explore this relationship in detail.
