Question

Given the following group of numbers, 8, 2, 9,4, 2, 7, 8, 0, 4, 1, which of the following

is/are true?
I. The mean is 5.
II. The median is 4.
III. The mode is 2.

Answer 1

Mode is 2,4 and 8( three numbers not 1)
Mean is 45/10 is 4.5
Median is4
The correct answer is only 2

Answer 2

III. The mode is 2

Explanation:

Mean: (8+2+9+4+2+7+8+0+4+1)/10 = 45/10 = 4.5

Median: (2+7)/2 = 9/2 = 4.5

Mode: There is no mode since 2 and 8 both appear twice (in other words, since they have the same frequency, it's bimodal)

The closest possible choice is III. The mode is 2, but keep in mind that since the data set is bimodal, there is no single mode.
