Answer
Mean=20.56
Mode=18.4
Range=23
Median=8.4
Work Step by Step
You have 33.8,10.8,18.4,21.4,18.4.
To find the mean divide by 5 because you have 5 values
$\frac{33.8+10.8+18.4+21.4+18.4}{5}$=$\frac{102.8}{5}$=20.56
To find the median you have to arrange the values from the least to greatest and find the middle number:
10.8,18.4,18.4,21.4,33.8. The middle value is 18.4
The range is the largest number minus the smallest number, so 33.8-10.8=23
The mode is the number that occurs the most which is 18.4.
Mean=20.56, Median=18.4, Range=23, Mode=18.4
