Montagem do Histograma
hist(df$height, col = "lightpink", main = "Histograma Altura dos Pokemons",
xlab= "Altura", ylab= "Frequência")
O histograma acima, na cor rosa (lightpink), indica a altura dos pokemons apresentados na tabela. Suas alturas variam entre próximo a zero a 150, com frequência máxima de 400 e mínima próxima a zero.
O modelo de histograma é indicado para a análise de variáveis quantitativas. No eixo X temos a mostargem da altura, enquanto do eixo y da frequência. Podemos perceber que nele há apenas uma moda, apresentado com 400 pokemons entre zero e 10 de altura, declica para a esquerda com (por volta de) 250 pokemons de altura entre 10 e 20 e então cai bruscamente. Portanto é um gráfico com precipício a esquerda e assimentria a direita.
