Ngahau Dot Plot

Kia ora. In Te Ngahere the whole class has been learning about dot plots. Dot plots are a type of graph that use dots as the data. For example in this pdf (winning dots) they have a dot plot and they are trying to measure the distance and the range of room 1 and room 2 ball throwing skills. When I was doing my DLO about this pdf (winning dots). I did not know what range meant. I thought that range meant the distance of the ball that traveled. But now I know what it means. The way you find the range is you have to get the lowest number and the biggest number and subtract the smaller number by the bigger number and the answer equals the range. Example if someone threw the ball 3 meters and someone else threw the ball 15 meters you do 15-13=12 so 12 is the range. I also could improve my DLO by explaining what the range meant clearer. Did you know what a dot plot was before you read my post?
