Answer:
median: 30
mean: 27
Step-by-step explanation:
If you put the data into order from small to big, you find the median by finding the exact middle of the list.
Here we have:
5,5,10,10,30,30,42,
42,48,48
This list has an even number of items. So it doesn't have one number in the middle, it has two. Here, the number is the same number, 30, so that is the median. (If there was one number in the middle that would be the median; if there were two different numbers in the middle, we'd average them.) THE MEDIAN IS IN THE MIDDLE.
To find the mean, you do what is commonly called finding the average. You add all the numbers and divide by the number of items in the list.
To find the MEAN, ADD AND DIVIDE.
5+5+10+10+30+30+42+42+48+48
= 270
Divide by 10 because there's 10 numbers in the list. 270/10 = 27
The mean is 27.
