What is the median for the following set of numbers? $3.27, $9.42, $6.15, $5.25, $7.62, $4.86, $2.94, $1.16
Answer: D - The median or the middle number when the numbers are in ascending order ($1.16, $2.94, $3.27, $4.86, $5.25, $6.15, $7.62, $9.42) for the set above is $5.70. Whenever there is an even number of entries in a set, putting two numbers in the middle of the ordered entries, those two numbers are averaged to find the median. The mean is about $4.07. There is no mode because each number occurs only one time in the set.
