I notice there is one graph that doesn’t really fit into A, B or C. There is one graph in A that doesn’t have lines connecting the dots so it not correct. One in B and a bunch in C don’t start at the bottom of the graph/paper. One of the B’s doesn’t stop for long enough. It barley even stops. The 2 B’s look very different.
Piper, these are the beginning of some good observations, but they are incomplete. You said, for example, that it is incorrect to leave the data points unconnected. Why? Also, you observed that some start at the bottom of the graph and some don’t. What are your conclusions about this? What do you think? Are both ways correct? Why or why not?
