Lecture 3 Homework

Homework 3: Pokemon Data Analysis

The following homework contains three questions, all of which require you to apply what you've learned about exploratory data analysis and visualizations. There is also a short discussion prompt for you to complete at the end. As always, please ask any of the mentors if you need help with this homework.

import pandas as pd import matplotlib.pyplot as plt import seaborn as sns import numpy as np

data = pd.read_csv("/work/Pokemon(1).csv") data.head()

What is the most common "Type 1" for all the Pokemon? Use the code cell below to figure this out.

(Hint: Use the function value_counts() to answer this question)

data['Type 1'].value_counts()

•

Using data from every Psychic type (meaning Type 1 OR Type 2 is Psychic), create a scatterplot graph for the "Attack" and "Special Attack" columns. What kind of a relationship do you see? Is it a strong or weak relationship? Positive or negative?

# First filter the dataset so that it just includes Psychic type Pokemon. # Then make your scatterplot. filtered = data[(data['Type 1'] == 'Psychic') | (data['Type 2'] == 'Psychic')] filtered.plot.scatter(x = 'Attack', y = 'Sp. Atk')

  scatter = ax.scatter(

What kind of relationship do you see?

There is a positive relationship between attack and special attack.

•

Using histograms, compare the distributions of "HP" for Pokemon that are and aren't legendary. What do you see here? Talk about the skewness, outliers, mode(s), etc.

(Hint: Use the hue argument for sns.histplot to specify whether or not a Pokemon is legendary)

data.hist(column = 'HP', by = 'Legendary')
