When trying to decide whether or not to see The Tourist, a question was raised about whether Johnny Depp, a star widely reputed to wear a lot of hats, was hatted, implying that hattendness would be a reasonable predictor for quality of Johnny Depp movie.
Unfortunately, the data does not seem to support the conclusion that quality of Depp movie can be predicted by his hattedness: Both classic and tragic Depp movies appear in both categories.
Roles were selected from Depp's IMDB page, a binary determination of "significant hattedness" was made (with 1 representing "hatted" and 0 representing "hatless"), and the IMDB cumulative rating as of 1/23/11 was taken. Absolutely no further data processing was attempted. See: Opportunities for future study.
Possible sources of error:
Depp's IMDB page may or may not be correct. All Depp roles were included, even those categorically unlikely to include hats (if hats predicated on Depp's personal love of hats), e.g. Spongebob Squarepants. Degree of hattedness is debateable — for the purposes of this study, headbands counted, as did Depp's hair in Edward Scissorhands, but masks did not. IMDB scores are not an objective rating of film quality; there's no way that Crybaby is a worse movie than Pirates of the Carribean.
Opportunities for further study:
A more thorough survey of Depp's oeuvre may uncover more instances of hattedness. Likewise, a more thorough study may allow us to develop a more nuanced hattedness metric, dependent upon duration and significance of hat wearing, which could be broadly applied to develop a universal hat measurement. The proportion of hattedness within Depp's films could also be compared to the hattedness of other actors, ultimately resulting in predicting the amount that hattedness contributes to the overall quality of a film. The study of hattedness, or hattery, or capology, is young and has many opportunities. With more funding, this data set could also be run through all sorts of pretty graphs and plots. But someone would also have to show me how to do that.
