To find the mean, add up all the numbers and divide by the total number of numbers:
Mean = (10 + 11 + 4 + 7 + 12 + 11 + 16 + 6 + 9 + 15) / 10 = 101 / 10 = 10.1
To find the median, first, reorder the numbers from smallest to largest:
4, 6, 7, 9, 10, 11, 11, 12, 15, 16
Since there are 10 numbers, the median is the average of the two middle numbers, which are the 5th and 6th numbers in the ordered list:
Median = (10 + 11) / 2 = 21 / 2 = 10.5
To find the mode, identify the number that appears most frequently in the set. In this case, the mode is 11, as it appears twice, while all other numbers appear only once.
Find the mean, median, and mode of the set of data. 10, 11, 4, 7, 12, 11, 16, 6, 9, 15 (2 points)
