To find the mean, we add up all the numbers in the data set and then divide by the total number of numbers:
15 + 13 + 9 + 9 + 7 + 1 + 11 + 10 + 13 + 1 + 13 = 102
Mean = 102 / 11 = 9.3 (rounded to the nearest tenth)
To find the median, we need to first put the numbers in order:
1, 1, 7, 9, 9, 10, 11, 13, 13, 13, 15
Since there are 11 numbers, the median is the middle number, which in this case is the average of the two middle numbers:
Median = (9 + 10) / 2 = 9.5
To find the mode, we need to determine which number appears most frequently in the data set:
The number 13 appears 3 times, which is more than any other number, so the mode is 13.
15 + 13 + 9 + 9 + 7 + 1 + 11 + 10 + 13 + 1 + 13 = 102
Mean = 102 / 11 = 9.3 (rounded to the nearest tenth)
To find the median, we need to first put the numbers in order:
1, 1, 7, 9, 9, 10, 11, 13, 13, 13, 15
Since there are 11 numbers, the median is the middle number, which in this case is the average of the two middle numbers:
Median = (9 + 10) / 2 = 9.5
To find the mode, we need to determine which number appears most frequently in the data set:
The number 13 appears 3 times, which is more than any other number, so the mode is 13.
