6-19.

Alan wants to convince his parents that he is doing well in math. His test scores are $83$, $90$, $58$, $71$, $82$, $91$, $82$, and $64$. Should he use the mean, median, or mode to convince them? Explain your reasoning and show your work.

Find the mean, the median, and the mode of Alan's test scores.

The mean is the average of Alan's test scores. The median is the middle number when the numbers are arranged numerically, or the average of the two middle numbers. The mode is the most re-occurring number in the set of data.

The mean is $77.625$, the median is $82$, and the mode is $82$. Which answer(s) would convince his parents that Alan is doing well in math?

Either the median or the mode because those scores are higher.
