To compute the mean (average) daily time that Sarah spent on her favorite social media site over the week, we can follow these steps:

1. **Sum the hours**: Add up the hours Sarah spent each day.
   \[
   1.5 + 2 + 1.25 + 2.5 + 2.75 + 3.25 + 2.5 = 15.75 \text{ hours}
   \]

2. **Calculate the mean**: Divide the total hours by the number of days (7).
   \[
   \frac{15.75}{7} = 2.25 \text{ hours}
   \]

**Answer**: The mean daily time that Sarah spent on her favorite social media site for one week is **2.25 hours**.
