This activity requires the Flash plug-in, which you can download for free from Macromedia's Web site. If you prefer, you can continue to work with your noodles in a non-interactive version of this activity, which doesn't require the Flash plug-in.
This time, there won't be one noodle in the middle -- there will be two! If you remove this middle pair, you'll have no noodles left.
Therefore, you'll need to draw a line midway between the two remaining noodles to play the role of the median. The length of this line should be halfway between the lengths of the two middle noodles.
Notice that this median still divides the set of noodles into two groups of the same size -- the six noodles shorter than the median and the six noodles longer than the median:
The major difference is that, this time, the median is not one of the original noodles; it was computed to divide the set into two equal parts.
Note: It is a common mistake to include this median in your data set when you've added it in this way. This median, however, is not part of your data set.
