In my last blog I talked about a simple chart on Morning Joe, which was presented by Steven Rattner. I submitted that when we see data presented in the media or especially by politicians, we should judge it in terms of how a researcher would have presented the same data (because of course researchers are free of bias...well let's leave that for another blog). I gave Mr. Rattner a pass last time, but his presentation of a chart on infrastructure was misleading and would only have pleased a client who wanted misleading data to prove a point.
In this case he presented a chart showing infrastructure spending as a percentage of GDP . It showed a massive drop from the high in the 1950's to the low of today. The chart had a y axis that went from 0% to 1.5% which made the drop easier to see. Nothing wrong with that (assuming those viewing the chart understood that it was not based on 0-100%).
