Frequency and Range is 85 Mean is 8 Mode is 0 Median is 4

Which average do you think is best to describe the results of this survey?

We think median number best reflects the average of this survey. When a data has one skewed number as this case, mean is influenced by that number. If mean is 8, as this case, the above average numbers of the CD owners are only 4 out of 20. The mode will give you 0 which doesn’t reflect the average of the survey results. When we remove top and bottom numbers as we normally do to get an average, 160-84 divided by 19 equals 4.

Would it be the best for all surveys? We are not sure about this question. There are many ways to take surveys some are not number based. In order to get an average number for the number based surveys, it is better to try mean, mode and median to see which numeral reflects the survey result best. Rely on one way to get an average for all survey is not appropriate.
