*note: features of less than 4% were not labeled
The values in this graph were calculated by dividing the feature subcategory by the toal amount of features marked in that category. For example the percentage of strong male particles or pronouncs used by men was found by diving the amount of pronons and particles marked strong male in songs sung by men by the total amount of particles or pronouns marked for gender in songs sung by men We chose to use percentages rather than counts to account for differences in amounts of particles and pronouns used.
Values were caculated the same way as for the bar graph but were further separated by year. Additionally, strong male and moderate male/neutral were combined into one male category and strong female and moderate female were combined into one female category.
Values were calculated the same way as for the other two graphs.
