Answer:
The Median is 10
The mean is 10.5
Step-by-step explanation:
To find the median, we need to arrange the data in an ascending or descending order.
In an ascending order, we have:
4, 8, 8, 12, 13, 18
The median is the middle number.
Since the number of data is even, the median is the mean of the two middle numbers.
The two middle numbers are: 8 and 12
The mean is (8 + 12)/2 = 20/2 = 10
The median is 10
The mean of the data is the sum of the data divided by the number of data.
The sum of data is:
4 + 8 + 8 + 12 + 13 + 18 = 63
The number of data is 6
Mean = 63/6 = 10.5
