Interest is in whether the weight class changes the likelihood of various types of fight results; for example, are lighter weight fights more likely to "go the distance" (last all rounds)?

+| decision_group |	aggregated groups of decision variable |
+| round	| how many rounds the fight lasted |

+
+: [mma_wtclass.csv](../data/mma_wtclass.csv)
+
+
+## Questions
+
+1. Are lighter weight fights more likely to end in a decision? 
+
+2. Which weight class is most likely to produce a knockout?
