Derrial Book Descriptive Personality Statistics

Derrial Book is a character from Firefly + Serenity.

This page summarizes crowd sourced ratings of their personality collected from users of the Statistical "Which Character" Personality Quiz. This website has recruited more than 3 million volunteers to rate characters on descriptive adjectives and other properties, which can be aggregated to create profiles that users can be matched to as part of a personality test. For more information about how the ratings were collected and how they are used, see the documentation.

Aggregated ratings for 400 descriptions

The table shows the average rating the character received for each descriptive item on a 1 to 100 scale and what that character's rank for the description is among all 1,750 characters in the database. It also shows the standard deviation of the ratings and how many different individuals submitted a rating for that description.

The lowest rating for any description in the table is 50.0 despite a 1 to 100 scale being used. This is because descriptions that had values lower than the midpoint were reversed. For example, a score of 1/100 for "hot (not cold)" is equivalent to a score of 100/100 for "cold (not hot)". This was done so that all the traits that are most distinctive for a character are at the top of the table.

Similar characters

The similarity between two characters can be calculated by taking the correlation between the lists of their traits. This produces a value from +1 to -1. With +1 implying that every trait one character is high on the other one is high on too, to an equal degree. And, -1 implying that if a character is high on specific trait, the other one is low on it. The 10 most and least similar characters to Derrial Book based on their crowd-sourced profiles are listed below with the correlation in parenthesis.

Personality types

Personality types according to various systems can be derived from the character's traits. Profiles for a personality type were computed by averaging together all responses from people who took the test and reported a given personality type and then this composite was matched to each of those profiles as if it was its own character (as was done above). Listed closest to worst match.
