The Median
Find the one in the middle. An informative resource explains how to determine the median of a set of numbers. Using both even and odd numbers of data points, the video covers the process of finding the middle number. Worksheets provide...
Corbett Maths
The Range
Spread the data out on the range. The short video provides a definition of the range. Using a data set of five numbers, the resource calculates the range.
Corbett Maths
The Mode
Most frequently prefer the mode. The resource defines the mode and shows how to determine it in a data set. Using another type of problem, the video develops a data set with a given mode and number of data points.

Mystery Dice
Dice aren't typically mysterious devices, but these dice are anything but typical. Scholars try to come up with dice that match given information on the relative frequency when they roll them a certain number of times. They must then...

How Long is 30 Seconds?
Is time on your side? Pupils come up with an experiment to test whether their classmates can guess how long it takes for 30 seconds to elapse. They divide the class data into two groups, create box-and-whisker plots, and analyze the...

Center of Population
Let the resource take center stage in a lesson on population density. Scholars use provided historical data on the center of the US population to see how it shifted over time. They plot the data on a spreadsheet to look the speed of its...
