Dataset:
The dataset can be downloaded from Kaggle. It contains information about Olympic events, athletes, medals, and participating countries.
Tools & Libraries:
- Python
- Pandas
- NumPy
- Matplotlib
- Seaborn
- Jupyter Notebook or Google Colab (Recommended)
1. Data Collection & Setup
Import Libraries and Load Dataset
# Import necessary libraries
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
# Load the dataset
data = pd.read_csv('/path/to/olympic_data.csv') # Replace with actual file path
# Preview the dataset
data.head()
Explanation:
- The Olympic dataset is loaded using pandas, and the first few rows are displayed to get an overview of its structure. This helps us understand the columns and data types we’ll work with.
2. Exploratory Data Analysis (EDA)
Overview of the Dataset
# Display dataset information data.info() # Check for missing values data.isnull().sum() # Basic statistical summary data.describe()
Explanation:
- We check for missing values and data types using
info()andisnull(). This step ensures we identify any inconsistencies or data cleaning needs. The statistical summary provides insights into numerical columns.
Top Countries by Medal Count
# Group data by countries and count medals
country_medals = data.groupby('Country')['Medal'].count().sort_values(ascending=False).head(10)
# Plot the top 10 countries
plt.figure(figsize=(10, 6))
country_medals.plot(kind='bar', color='gold')
plt.title('Top 10 Countries by Medal Count')
plt.xlabel('Country')
plt.ylabel('Number of Medals')
plt.show()
Explanation:
- This visualization highlights the countries with the highest medal counts, showing historical dominance in the Olympics. Grouping and sorting data helps us focus on the top-performing nations.
3. Data Cleaning & Preprocessing
Handle Missing Values
# Fill missing values in critical columns
columns_to_fill = ['Medal', 'Age', 'Event']
data[columns_to_fill] = data[columns_to_fill].fillna('Unknown')
# Drop duplicates
data.drop_duplicates(inplace=True)
Explanation:
- Missing values are filled with placeholders to ensure data integrity. Dropping duplicates removes redundant records, improving dataset quality.
Feature Engineering
# Create a new column for medal type encoding
medal_mapping = {'Gold': 3, 'Silver': 2, 'Bronze': 1, 'Unknown': 0}
data['Medal_Score'] = data['Medal'].map(medal_mapping)
Explanation:
- Numerical encoding is applied to medal types to facilitate analysis and visualization. For instance, Gold is given the highest score (3) for significance.
4. Data Visualization
Medals Over Time
# Group data by year and count medals
yearly_medals = data.groupby('Year')['Medal'].count()
# Plot medals over time
plt.figure(figsize=(12, 6))
plt.plot(yearly_medals, marker='o', color='blue')
plt.title('Total Medals Over Time')
plt.xlabel('Year')
plt.ylabel('Number of Medals')
plt.grid()
plt.show()
Explanation:
- This line plot shows how the number of medals has changed over the years. Significant spikes may correspond to specific events like the addition of new sports.
Gender Participation Analysis
# Group data by gender
gender_participation = data['Gender'].value_counts()
# Plot gender participation
plt.figure(figsize=(8, 6))
gender_participation.plot(kind='pie', autopct='%1.1f%%', colors=['blue', 'pink'], startangle=140)
plt.title('Gender Participation in Olympics')
plt.ylabel('')
plt.show()
Explanation:
- A pie chart visualizes gender participation, providing insights into the representation of male and female athletes over the years.
Top Athletes by Medals
# Top athletes by total medals
top_athletes = data['Athlete'].value_counts().head(10)
# Bar plot for top athletes
plt.figure(figsize=(10, 6))
top_athletes.plot(kind='bar', color='green')
plt.title('Top 10 Athletes by Medals')
plt.xlabel('Athlete')
plt.ylabel('Number of Medals')
plt.show()
Explanation:
- This bar plot showcases the top athletes with the most medals, reflecting their dominance in Olympic history.
