Answer:
Mean = 14.6
Median = 13.5
Step-by-step explanation:
Mean
Add the number and divide the answer by how many numbers are there.
20+14+6+25+18+13+19+10+9+12
= 146
How many numbers = 10
So 146/10
= 14.6
Median
Arrange in ascending or descending order..
6, 9, 10, 12, 13, 14, 18, 19, 20, 25...
Take the middle number....then that is median
In this case, there are 2 numbers...so add and divide by 2.
13+14 = 27
27/2
= 13.5
