This article is talks about tackling the welfare incentives by making migrants wait four years before claiming welfare benefits in certain countries in Europe and kicking out jobless migrants after six months in those same countries. Here there are two verticle bar graphs shown. Both bar graphs have a proportionate Y axis ranging from 0% to 90 %, in equal in equal frequencies. Both graphs X axis are clearly labeled and appear to be separated equally in the spacing aspect. Both graphs have a title, clearly showing the difference between both graphs. One key aspect of these graphs in particular are the need for a key. The keys in these two graphs clearly depict different views of the poll, these are: support, oppose, and don't know. Without the keys the viewer would be very confused of what information is depicted and would need much further clarification. These graphs are thus properly constructed and appear to be good graphs however, I do see a problem here. The source of the data is not divulged and thus leads us to wonder how this poll was conducted. We have no way of knowing if the collection of the data was collected appropriately and therefore the book clearly states we should not rely on it to yield any information (Triola, 2015).
