Find the median and mean of the data set below:18, comma, 18, comma, 12, comma, 47, comma, 1018,18,12,47,10
Question
Find the median and mean of the data set below:
18, 18, 12, 47, 1018, 18, 12, 47, 10
Solution
Sure, let's start with arranging the data set in ascending order: 10, 12, 18, 18, 47.
-
To find the median, which is the middle number in a sorted list, we see that the middle number in our data set is 18. So, the median is 18.
-
To find the mean (average), we add up all the numbers and then divide by the count of numbers. So, (10 + 12 + 18 + 18 + 47) / 5 = 21.
So, the median of the data set is 18 and the mean is 21.
