Find the median and mean of the data set below:
8, comma, 6, comma, 28, comma, 25, comma, 42, comma, 8, comma, 30
8,6,28,25,42,8,30
Answer
Attempt 1 out of 2
Median =
Mean =
To find the median, we first need to arrange the data set in numerical order:
6, 8, 8, 25, 28, 30, 42
The median is the middle value in a set of numbers, when they are listed in order. Since we have seven numbers, the middle number is the fourth number in this case:
Median = 25
To find the mean (average), we add up all the numbers in the data set and then divide by the total number of values:
Mean = (6 + 8 + 8 + 25 + 28 + 30 + 42) / 7
Mean = 147 / 7
Mean = 21
Therefore, the median of the data set is 25 and the mean is 21.
