This worksheet presents four boxes, each containing an illustration of a fleet of birds in flight, numbered on their underbellies. The same birds are then depicted perched on a wire beneath, without any numbers. Students must accurately rewrite these numbers on the unmarked birds in a sequence and then compute the mean, median, and mode.

Mean, median, and mode describe different kinds of "averages." The mean is what most people think of as the average - you add up all the numbers and then divide by how many numbers there are. The median is the middle number in a list - half of the numbers are more significant, and half are smaller. The mode is the number that appears most often in a list.

By mastering these concepts, you'll be able to organize data, understand the 'typical' value in a set of numbers, and even visualize data. These are essential skills in many fields, from statistics to business analytics.
