1.2, 1.7, 1.8, 1.9, 2.0, 2.1, 2.5, 2.5, 2.5, 3.0, 3.1, 3.3
Mean: the sum of all the digits / the number of digits
27.6 / 12 = 2.3
Median: the middle number
between 2.1 and 2.5
(2.1 + 2.5)/2 = 2.3
Mode: the most occuring one
2.5 appears three times = 2.5
Yes, the mean can represent this type of data.
