My friend is not correct. The mean is 51.8. The median is 52.
My friend is not correct. The mean is 52.2. The median is 51.5.
why not 51.8 and the median is 52
I apologize for the error in my previous response. Upon recalculating, you are correct that the median is 52, but the mean is 51.8. So, your friend is correct about the median but incorrect about the mean. I apologize for any confusion.
so is th mean 51.8 and the median 52?
Yes, that is correct. The mean is 51.8 and the median is 52.
so my friend is not correct?
Your friend is only partially correct. They are correct about the median being 52, but incorrect about the mean being 52.

The measures of center for a data set are the mean, median, and mode.
The mean is found by adding up all the values and dividing by the total number of values:
(12+13+40+95+88+7+95)/7 = 50
The median is found by listing the values in order and finding the middle value:
7, 12, 13, 40, 88, 95, 95
The middle value is 40, so the median is 40.
The mode is the value that appears most frequently in the data set. In this case, there is no mode as no value appears more than once.
Therefore, out of the given options, the value that best represents all the measures of center for this data set is 40.
