I understand how to get mean, median,mode, and range. I just dont realy get what this is asking

campbell_st · Answer

they are asking which statistic best describes the centre of the data. 

mean is best when the data is grouped

median is best when outliers occur

mode is best for categorical data

Range is a measure of spread or location.

ok, I think I understand that

campbell_st · Answer

if the find the mean... 91 has a significant influence on the mean... 

the mean without 91 is 55 with 91 it jumps to 62.5 so it has a big effect on the mean.
