Almost all of the students' scores are below the average. Therefore, in this case the mean is not a good representative of the central tendency of this sample. The median, on the other hand, is the value which is such that half the scores are above it and half the scores below. So in this example, the median is 8. There are four scores below and four above the value 8. So 8 represents the mid point or the central tendency of the sample.
