Answer:
(a) The mean is:
The sum of the values: 1.8 + 5 + 6.3 + 8 + 8 + 4.8 + 2.8 + 4.8 = 41.5
The sum divided by the number of values: 41.5 ÷ 8 = 5.1875
(b) The median is:
The values in numerical order: 1.8, 2.8, 4.8, 4.8, 5, 6.3, 8, 8
The mean of the two middle values: (4.8 + 5) ÷ 2 = 4.9
(c) The mode is:
The values in numerical order: 1.8, 2.8, 4.8, 4.8, 5, 6.3, 8, 8
The values that repeat most often: 4.8, 8 (both appear twice)
