The number of surfer’s special burritos served was sampled during a dinner period 5:00 p.m. – 8:30 p.m. at a taco shop on a weekday. Below is the sample:
12 7 5 14 9 2 12 11 5 15
20 14 9 21 14
From this data set, compute the sample mean, median, mode and midrange. Compute the 1st
quartile and 3rd and interpret their meanings.

Okay, for the mean, add up all the numbers, then divide that number by number of numbers in the data set.

The mode is the number that appears the most often in the data set.

median: list all the numbers in order of greatest to least, and cancel the ends until you have the middle number.  If there are two middles, then take the mean of them.

I'm not entirely sure of how to do the others, maybe you could ask everyone on chat.
