Answer:
The mean = 14.3. median = 15.5 and the range = 10.
Step-by-step explanation:
10, 16, 19, 13, 12, 17, 16, 15, 9, 16
The mean = sum of the 10 numbers / 10 = 143/10 = 14.3.
Find the median by arranging in ascending order:
9, 10, 12, 13, 15, 16, 16, 16, 17, 19
The median is the mean of the 2 middle numbers = (15 + 16)/2
= 15.5.
The range = highest - lowest number = 19 - 9 = 10.
