For my class project, I used data from civil birth registration in New York state. The objective of this class project is to analyze ranked baby names that fall below 50th place and those within or up to the 50th rank. I used a decision tree for my analysis. I found the minimum split was at 20 and maximum to set 3 in order to have more clarity and less branches. I found that a majority of baby names were ranked below 50. They also were not of the ethnicity of asian or non-hispanic. The rarest probability of someone’s baby name being found in the data set were below rank 50, asian ethnicity, and not male. In conclusion, I discovered that the rank of the baby’s name doesn’t significantly impact whether they have a rare name, as both the highest and lowest probabilities were observed among names ranked below the top 50.
