Representation of Data (Graphs)
Majority of people or groups of people use graphs to portray their data that they have calculated. These graphs can be similar or different in a lot of way. With graphs, a person can tell if the display is reliable data or not. There are specific details that one can find to ensure that the graph has data that is correct.

This is an example (Image 1) of a good graph because it shows what it is calculating and shows a calculation for every year. It tells the viewers what the X and Y are standing for and it is a very easy graph to read.

As seen in Image 2 a person can tell this is an example of a bad graph. Looking at the graph above it is hard to understand what they are calculating and what its purpose is. The visual for this graph is so unappealing because it doesn't tell you what it is computing. It is hard to tell what level each to the "Halons" are at except for the Yellow bar.
Through my experience with graphs I have always perceived them to be correct with the information that they display. Until recently I have never known graphs to be biased and wrong. It astonished me to how they could be so deceiving. It is very important to be able to tell if the graph is not biased and has very factual evidence that supports it.

I've never seen a graph like the second example. If I saw that I'm sure I would not know what to think. Interesting thought that most of the time we view information on a graph as factual regardless of what the graph is.
ReplyDeleteOkay James, a good start to a discussion, though I would have liked you to go more in depth. There are so many graphs related to ozone depletion! A couple of points:
ReplyDelete-Instead of writing "URL" write "Image Source" and then link it to the actual URL like you have above -Make sure you are more specific about the graph/ diagram you are referring to. For this, it's better to label them each with "Figure 1," "Figure 2," etc. In the text, refer to them as such with phrases such as: "As seen in Figure 1..." or "Turning our attention to Figure 2, which illustrates..." etc.
-Do a quick spell/ grammar check, paying attention to the little details will make the post look more professional, remember your audience is basically the entire world, since your post is public.
Keep up the good work
