Find the mean medium and mode of the data set round to the nearest tenth 15 13 9 9 7 1 11 10 13 1 13

Answer 1

To find the mean, we first add up all the numbers in the data set and then divide by the total number of values.

Mean:
(15 + 13 + 9 + 9 + 7 + 1 + 11 + 10 + 13 + 1 + 13) / 11 = 102 / 11 ≈ 9.3

Next, we need to find the median, which is the middle value when the data set is ordered from least to greatest.

Median:
1, 1, 7, 9, 9, 10, 11, 13, 13, 13, 15

There are 11 values in the data set, so the median is the average of the 6th and 7th values:
(9 + 10) / 2 = 19 / 2 = 9.5

Finally, we find the mode, which is the number that appears most frequently in the data set.

Mode:
The number 13 appears the most in the data set, occurring three times.

Therefore, the mean is approximately 9.3, the median is 9.5, and the mode is 13.
