To calculate the mean, we need to sum up all the numbers and then divide by the total number of values.

The sum of the numbers is: 11 + 9 + 7 + 6 + 8 + 2 + 15 + 1 + 12 + 15 + 14 = 100.

There are 11 values in the set.

Mean = sum / total number of values = 100 / 11 ≈ 9.1.

To calculate the median, we need to arrange the numbers in ascending order first.

1, 2, 6, 7, 8, 9, 11, 12, 14, 15, 15.

There are 11 values, so the median will be the average of the 6th and 7th values.

Median = (8 + 9) / 2 = 8.5.

To find the mode, we need to determine which value(s) appear(s) most frequently in the set.

In this case, the number 15 appears twice, while the rest of the numbers appear only once.

Therefore, the mode is 15.

Mean: 9.1
Median: 8.5
Mode: 15

Answer 3

Apologies for the mistake in my previous response. Let me recalculate the mean, median, and mode correctly.

To calculate the mean, we need to sum up all the numbers and then divide by the total number of values.

Sum of the numbers: 11 + 9 + 7 + 6 + 8 + 2 + 15 + 1 + 12 + 15 + 14 = 100.

Total number of values: 11.

Mean = sum / total number of values = 100 / 11 ≈ 9.09.

To calculate the median, we arrange the numbers in ascending order first.

1, 2, 6, 7, 8, 9, 11, 12, 14, 15, 15.

There are 11 values, so the median will be the middle value, which is 9.

Median: 9.

To find the mode, we need to determine which value(s) appear(s) most frequently in the set.

In this case, 15 appears twice, while the rest of the numbers appear only once.

Therefore, the mode is 15.

Mode: 15.

Corrected values:
Mean: 9.09.
Median: 9.
Mode: 15.
