This study is a survey study which aims to determine underlying causes of anger and the anger levels of individuals, in the sample cases and mood-states defined in the research. 255 people participated by filling in forms developed by the researcher. They were asked to rank 6 mood-state expressions between 1 and 6, to classify 23 sample case expressions between 1 and 4. Using Microsoft Office Excel 2016, responses given to mood-state expressions were examined with rank-order and given to sample case expressions were examined with classifying judgment with respect to gender and marital status. The findings of rank-order judgment scaling revealed that all participants get angry most when they are treated unfairly and they get angry least when they are criticized. It was also found that females got angry more at being neglected, and males got angry more at arrogance and mistrust. It was concluded that married people got angry more at being neglected; unmarrieds got angry more at mistrust. The findings of classifying judgment scaling showed that all participants get angry the most when unnecessary and offending comments are made about their families. They get angry the least when their partners are fan of any subject. It also has been seen that married participants chose Ignoring the subjects that I care about the most and those who are unmarried chose 'Making unnecessary and offending comments about my family' the most.
