To calculate the mean of the data set, you sum all the values and then divide by the number of values.

Given dataTo calculate the mean of the data set, you sum all the values and then divide by the number of values.

Given $5, 8, 15, 7, 10, 22, 3, 1, 15$

1. Sum of the values: $5 + 8 + 15 + 7 + 10 + 22 + 3 + 1 + 15 = 86$

2. Number of values: $9$

3. Mean: $\text{Mean} = \frac{86}{9} \approx 9.56$

So, the mean of the data set is approximately $9.56$.
