Introdução

Atividade 4 - uma qualitativa versus uma quantitativa.

Este relátorio é sobre a base de dados df-pokemon, será analisado o poder de defesa e ataque dos grupos de tipos de pokemons.

Passo 1 - Carregar as bibliotecas

library(readxl)
library(flextable)
library(dplyr)

## 
## Attaching package: 'dplyr'

## The following objects are masked from 'package:stats':
## 
##     filter, lag

## The following objects are masked from 'package:base':
## 
##     intersect, setdiff, setequal, union

Passo 2 - Carregar o banco de dados

load("~/Base_de_dados-master/df_pokemon.RData")

As primeiras linhas do banco de dados

df %>% head() %>% data.frame() %>% flextable()

Duas Qualitativas

Vamos fazer a análise de duas variáveis qualitativas.

tabela = table(df$type_1,df$defense)

O boxplot

Conclusão

Ao agrupar as variáveis qualitativas “attack” e “defense” pela variável qualitativa “type_1”, foi possível calcular a média, mediana e o desvio padrão da força de ataque e defesa de cada grupo de pokemons, identificando quais grupos são mais coesos, isso é, têm forças de ataque ou defesa parecidos, se são bem variados e se têm outlier(s).

Para isso, foi feito um gráfico de caixas onde obtemos essas informações de forma mais visual e integral. Assim, é possível analisar a coesão dos grupos para cada variável qualitativa. No ataque a maior parte dos grupos são bem equilibrados, têm a caixa dividida ao meio e a caixa centralizada à linha pontilhada, tendo outliers presentes apenas nos grupos fairy, normal, psychic e steel e sendo o grupo rock com o maior máximo.

Na defesa, os grupos parecem ser muito variados, as caixas estão, em sua maioria, descentralizadas tanto com o total, quanto com a mediana. Há também mais outliers, estão presentes no grupo fire, ice, normal, psychic, rock e water e o grupo com o maior máximo é o steel.

Introdução

Atividade 4 - uma qualitativa versus uma quantitativa.

Este relátorio é sobre a base de dados df-pokemon, será analisado o poder de defesa e ataque dos grupos de tipos de pokemons.

Passo 1 - Carregar as bibliotecas

Passo 2 - Carregar o banco de dados

As primeiras linhas do banco de dados

Duas Qualitativas

Vamos fazer a análise de duas variáveis qualitativas.

Perguntas:

1. Qual tipo (da variável tipo1) tem o ataque mais forte

2. Qual tipo (da variável tipo1) tem a defesa mais forte

Variável resposta: attack, defense

Variável explicativa: type_1

Qualitativa versus Quantitativa

Conclusão

Na defesa, os grupos parecem ser muito variados, as caixas estão, em sua maioria, descentralizadas tanto com o total, quanto com a mediana. Há também mais outliers, estão presentes no grupo fire, ice, normal, psychic, rock e water e o grupo com o maior máximo é o steel.
