To find the mean, we sum up all the numbers and then divide by the total number of numbers.
Sum of the numbers: 3 + 15 + 3 + 3 + 1 + 11 + 2 + 8 + 3 + 7 + 15 = 71
Total numbers: 11
Mean = 71 / 11 ≈ 6.5

To find the median, we first arrange the numbers in ascending order: 1, 2, 3, 3, 3, 3, 7, 8, 11, 15, 15
Since there are 11 numbers, the median is the average of the two middle numbers: (3 + 7) / 2 = 5

To find the mode, we look for the number that appears most frequently.
The number 3 appears most frequently in the data set, so the mode is 3.

Apologies, I made an error. Let me recalculate.

I apologize for any confusion caused in my previous response.
