The dataset below is made up of 7 points, all of which are moveable. You can move more than one point at once by holding "Ctrl" and clicking the points you need.
Some suggested questions are:
- What will happen to each average and the range if I move all the points up by 1? Down by 1? Up by 20?
- Where do I have to move <pick a point> so that the mean is an integer? To make the mean <pick a value>
- Where can I move <pick a point that’s not the median> so that the median doesn’t change?
- Where can I move <pick a point which isn’t the first or last> so that the range doesn’t change?
- How can I change the data so that it has a mode? More than one mode?
- What’s going on with the {}?
