1. **State the problem:** Find the mean (average) of Victor Wembanyama's NBA Finals blocks per game given the scores: 3, 4, 3, 5. 2. **Formula for mean:** The mean of a set of numbers is given by $$\text{mean} = \frac{\text{sum of all values}}{\text{number of values}}$$ 3. **Calculate the sum:** Add all the blocks together: $$3 + 4 + 3 + 5 = 15$$ 4. **Count the number of values:** There are 4 games. 5. **Calculate the mean:** $$\text{mean} = \frac{15}{4}$$ 6. **Simplify the fraction:** $$\frac{15}{4} = 3.75$$ 7. **Interpretation:** On average, Victor Wembanyama had 3.75 blocks per game in the NBA Finals.
