1. Contexto

Harry Potter é uma série de 7 livros de fantasia escrita pela autora J.K Rowling, que foram adaptados em 8 longas cinematográficos. Desde o lançamento do primeiro romance, “Harry Potter e a Pedra Filosofal”, em 26 de junho de 1997, os livros ganharam uma imensa popularidade, aclamação da crítica e foram um sucesso comercial em todo o mundo. Até maio de 2015, já haviam sido vendidas 450 milhões de cópias ao redor do mundo, tornando a série um best-seller, sendo traduzida para 73 idiomas.

2. História

A história dos livros e filmes se passam ao redor do jovem órfão Harry James Potter, que descobre em seu aniversário de 11 anos que é um bruxo. O menino vai para o mundo da magia, onde poderá estudar na Escola de magia e bruxaria de Hogwarts. Os livros vão acompanhar as aventuras do Harry ao longo de sua adolescência onde ele deverá aprender a superar seus problemas como bruxo na escola de bruxaria, no mundo mágico e os problemas de qualquer adolescente comum como: amizades, paixões e a puberdade.

A Escola de Magia e Bruxaria de Hogwarts foi fundada por quatro grandes bruxos: Godrico Gryffindor, Helga Hufflepuff, Rowena Ravenclaw e Salazar Slytherin. Suas personalidades e os critérios para admissão no ensino deram origem a quatro casas, conforme seus sobrenomes, para abrigar os estudantes.

Os alunos são encaminhados para uma das Casas por meio da decisão do Chapéu Seletor, um artefato mágico capaz de ler a ambição de um indivíduo. Seu julgamento, por vezes impreciso, leva os estudantes para uma das quatro casas de Hogwarts: Grifinória, Sonserina, Lufa-Lufa e Corvinal .

Análise dos dados.

A Gliffindor (Grifinólia) é a casa que possui mais personagens?

HarryPotter %>%
  group_by(House) %>%
  summarise(contagem = n()) %>%
  ggplot(aes(x = House, y = contagem, label = contagem)) + 
  geom_bar(stat = "identity", fill = "green", color = "red") +
  geom_label() + coord_flip()

Sim. Dentre as casas de magia a Gryffindor (Grifinólia) é a que possui mais personagems (38)

Qual casa tem mais personagens do gênero masculino e qual possui mais do gênero feminino?

HarryPotter %>%
  group_by(House, Gender) %>%
  summarise(contagem = n()) %>%
  ggplot(aes(x = House, y = contagem, fill = Gender, label = contagem)) + 
  geom_bar(stat = "identity", fill = "green", color = "red") +
  geom_label() + coord_flip()

Dentre as casas de magia a Gryffindor (Grifinólia) é a que possui mais personagens do gênero masculino (26) e do gênero feminino (12)

Existe dominância de status sanguineo em alguma das casas?

HarryPotter%>%
  filter(`Blood status` %in% c("Pure-blood","Half-blood","Muggle-born","Part-Human (Half-giant)","Half-blood or pure-blood",
                               "Unknown","Part-Goblin","Muggle-born or half-blood[","Quarter-Veela","Muggle","Squib","Pure-blood or half-blood")) %>%
  group_by(`Blood status`,House) %>%
  summarise(
    contagem=n()
  )%>%
  ggplot(aes(x=`Blood status`, y=contagem, fill = House,label=contagem))+
  geom_bar(stat= "identity", position="dodge")+
  geom_label(position= position_dodge(width=1),alpha=0.5)+
  theme_calc()

Há dominância do tipo “Pure-blood” na casa Gryffindor (Grifinolia)

Hipóteses

Para os testes de hipótese vamos associar duas variáveis qualitativas categóricas

Primeira hipótese

Há relação entre o gênero (Gender) e a escolha da casa (House)?

– Variável de interesse: casa (House)

– Variável explicativa: gênero (Gender)

Hipótese nula (H0): Não há relação (associação) entre o gênero e a escolha da casa.

Hipótese alternativa (H1): Há relação (associação) entre o gênero e a escolha da casa.

alpha = 0,05.

Se pvalor <= 0,05 Rej H0.

Se pvalor > 0,05 Não Rej H0.

Escolha do teste

Para isso vamos primeiro fazer uma tabela relacionado as duas variáveis:

#######Tabela relacionando as duas variáveis
Tabela_Gender_House <- table(HarryPotter$Gender,HarryPotter$House)
Tabela_Gender_House

##         
##          Beauxbatons Academy of Magic Durmstrang Institute Gryffindor
##   Female                            3                    0         12
##   Male                              0                    1         26
##         
##          Hufflepuff Ravenclaw Slytherin
##   Female          5         9         6
##   Male            8         9        21

Como a tabela é maior que 2 x 2 com mais de duas categorias em uma das variáveis, o teste escolhido é o Teste exato de Fisher com aproximação híbrida.

##   Male            8         9        21

Teste exato de Fisher:

# fisher teste
# usando aproximação hibrida pois a tabela é maior que 2x2

teste_fisher1 <- fisher.test(TT1, hybrid = TRUE)
teste_fisher1

## 
##  Fisher's Exact Test for Count Data hybrid using asym.chisq. iff (exp=5,
##  perc=80, Emin=1)
## 
## data:  TT1
## p-value = 0.06996
## alternative hypothesis: two.sided

Análise do resultado

p-valor = 0.06996 portanto não rejeita a hipótese nula.

Discussão: Não há relação entre o gênero e a escolha da casa

Segunda hipótese

Há relação entre o Status sanguineo (Blood status) e a escolha da casa (House)?

– Variável de interesse: casa (House)

– Variável explicativa: Status sanguineo (Blood status)

Hipótese nula (H0): Não há relação (associação) entre o Status sanguineo (Blood status) e a escolha da casa (House).

Hipótese alternativa (H1): Há relação (associação) entre o Status sanguineo (Blood status) e a escolha da casa (House).

alpha = 0,05.

Se pvalor <= 0,05 Rej H0.

Se pvalor > 0,05 Não Rej H0.

Teste exato de Fisher

#teste exato de fisher usando aproximação hibrida
teste_fisher2 <- fisher.test(TT2, hybrid = TRUE, workspace = 200000000)
teste_fisher2

## 
##  Fisher's Exact Test for Count Data hybrid using asym.chisq. iff (exp=5,
##  perc=80, Emin=1)
## 
## data:  TT2
## p-value = 0.001396
## alternative hypothesis: two.sided

Análise do resultado

p-valor = 0,001396 portanto rejeita a hipótese nula (H0)

Dicussão do resultado: Há relação entre status sanguineo e escolha da casa

5. Conclusão

A partir dos resultados obtidos podemos chegar nas seguintes conclusões: Grifinólia (Gryffindor) é a casa que mais possui personagens (38 no total) e a que mais possui personagens masculinos e femininos em números quantitativos. No entanto, a Sonserina (Slytherin) é a que mais possui personagens masculinos quando se trata da proporção feminino por masculino, sendo 21 personagens homens e apenas 6 personagens mulheres e a casa Cornival (Raveclaw) possui uma distribuição igualitária possuindo a mesma quantidade de mulheres e homens. Além disso, podemos perceber que existe uma dominância de personagens puro sangue (pure-blood) nas casa Sonserina e Grifinólia, e meio-sangue (half-blood) na casa Cornival.

E ao realizarmos o teste de Fisher podemos perceber que existe relação do tipo de sangue na escolha das casas, mas não existe relação do gênero com a escolha das casas.
