The research is a good idea, an investigation of the halo effect. The population of graders wasn't mentioned, that can have a huge effect on the result. Also, was 1000 people enough to analyze 12 variables?
However, I have to say, the graphs are ugly. Eg, spikes aren't good, you could have gone with with a bar chart. Also, 3d graphs are unneeded, and in general are very hard to do right. They can't convey much information. With just 2x2 variables, there are 4 datapoints. That would be fine on a 2d picture.

Otherwise keep on with the research...
