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