Which statement below is most accurate in describing the center of the distribution of study hours?
75%-
The median should be used to describe the center, because the values on the horizontal axis can be split exactly in the middle
The mean should be used to describe the center because it may produce a decimal value, which is more accurate than the median
The mean should be used to describe the center because the data is roughly symmetric
The median should be used to describe the center because, since the data is skewed, the middle outcome may more accurately describe a typical value in
the distribution
