Atividade4 sobre os dados de Pokémon
Decidi fazer a atividade 4 com os dados de Pokémon. Iniciei exportando o endereço:
load("C:/Users/Ana Beatriz/Downloads/Base_de_dados-master/df_pokemon.RData")Escolhi as variáveis qualitativas ‘type_1’ e ‘type_2’
df$type_1<-as.factor(df$type_1)
df$type_2<-as.factor(df$type_2)Fazendo isso, formei uma tabela cruzada o qual tinha informações sobre o tipo 1 e tipo 2 das centenas de pokémons existentes.
TabelaComparativaPokemon<-table(df$type_1,df$type_2)

Observando a tabela, podemos descobrir diversas informações sobre o mundo Pokémon e a natureza deles!
Das informações dadas é que 42% dos pokémons que tem grass (grama) como tipo 1, tem poison (veneno) como tipo 2, um exemplo disso seria o Bulbasaur e suas evoluções, que inicia nos primeiros nÃveis as suas habilidades venenosas!
Outra informação que podemos reconhecer é que de todos pokémons tipo 1 normal, aproximadamente 12% tem como tipo 2 fairy (fada).Casos fofos como esse seriam: Igglybuff, Jigglypuff e Wigglytuff!
Por último, quis pegar um caso bem raro, que faz parte dos, aproximadamente, 2,08% de todos os pokémons tipo 1 de water (água) que tem como tipo 2 steel (aço), que é o Empoleon. Empoleon não é bem conhecido pois foi introduzido na geração IV, porém é bem único por ser o único pokémon a ter essa combinação!
Com isso, obrigada por ler até aqui!
