Transcribed Image Text:**Sample Data**
This table presents data comparing the graduation timeline between students who transferred from community college and those who did not transfer.
| | Community College Transfer | No Transfer |
|-----------------------------------------|----------------------------|-------------|
| **n** | 270 | 1152 |
| **Sample mean time to graduate, in years** | 5.46 | 4.41 |
| **Sample standard deviation time to graduate, in years** | 1.131 | 1.013 |
- **n**: Sample size, representing the number of students in each category.
- **Sample mean time to graduate, in years**: The average number of years taken to graduate.
- **Sample standard deviation time to graduate, in years**: Measures the amount of variation or dispersion in the graduation time.
**Summary:**
Students who transferred from community colleges had a mean graduation time of 5.46 years with a standard deviation of 1.131 years. In contrast, students who did not transfer had a mean graduation time of 4.41 years with a standard deviation of 1.013 years.
