In Emma's sociology discussion group 4 of the 5 students are between the ages of 19 and 23; the fifth student is 54 years old. If Emma wants to report the statistic that best represents the "average" age for her discussion group, she should report either
A) the mean or the median, because these numbers are typically the same.
B) the mean or the mode, because these number are not affected by extreme scores.
C) the median or the mode, because these numbers will be more representative.
D) the mean or the standard deviation, so additional statistics can be calculated.
