Find the mean for each set of data. Round to the nearest tenth if necessary 12, 20, 8, 15, 16, 14, 7, 5, 11, 8, 14
i realy need help on this i keep on getting 12 as the median but the answer choices don't have 12, could u guys help me please
Are you supposed to find the mean or the median? Are you clear about the difference?
Of course, I can help you with that! To find the mean for a set of data, you need to add up all the numbers and then divide the sum by the total number of values.
Let's go step by step through the process for the given set of data: 12, 20, 8, 15, 16, 14, 7, 5, 11, 8, 14.
1. Add up all the numbers:
12 + 20 + 8 + 15 + 16 + 14 + 7 + 5 + 11 + 8 + 14 = 140
2. Determine the total number of values in the set, which is 11 in this case.
3. Divide the sum (140) by the total number of values (11):
140 / 11 = 12.7 (rounded to the nearest tenth)
So, the mean of the given set of data is 12.7 (rounded to the nearest tenth).
It seems like you may have confused the median (middle value) with the mean (average). The median is the middle value when the data is arranged in ascending or descending order. However, to find the mean, you need to add up all the numbers and divide by the total count.
