1. Project Overview

Goal: [Briefly state the main objective of this project. For example: “To analyze customer churn and identify key drivers for a subscription-based service.”]

Key Findings: [Summarize the 1-3 most important insights you discovered. For example: “Found that customers on a monthly plan without auto-renewal are 50% more likely to churn. Implemented a predictive model with 85% accuracy.”]

2. Problem Statement

[Describe the business problem or research question you are addressing. Why is this problem important to solve? What are the expected outcomes or benefits?]

3. Data Sourcing

[Describe where you got your data. Was it from a public dataset (e.g., Kaggle, UCI Repository), a private database, or scraped from the web? Provide links if possible.]

4. Data Cleaning & Preprocessing

[Detail the steps you took to clean and prepare the data for analysis. This is a great place to show off your technical skills.]

Example Steps:

  • Handled missing values by…
  • Corrected data types for columns like date and category.
  • Removed duplicate entries.
  • Engineered new features, such as customer_lifetime_value.

Here is a sample of the code used for cleaning:

import pandas as pd

# Load the dataset
df = pd.read_csv('your_data.csv')

# Fill missing values in the 'age' column with the mean
mean_age = df['age'].mean()
df['age'].fillna(mean_age, inplace=True)

# Drop rows with any remaining nulls
df.dropna(inplace=True)

print("Data cleaning complete. Shape of the new data:", df.shape)

5. Exploratory Data Analysis (EDA)

[This is where you showcase your findings with visuals and statistics. Describe the distributions, correlations, and trends you discovered in the data.]

Key Insight 1: [Name of Insight]

[Description of the insight.]

Figure 1: A brief description of what this chart shows.

Key Insight 2: Process Flow

[You can even use Mermaid to create diagrams directly in your post.]

6. Modeling & Evaluation (Optional)

[If you built a machine learning model, describe your approach.]

  • Model Selection: [Explain why you chose a particular algorithm (e.g., Logistic Regression, Random Forest, etc.).]
  • Feature Importance: [Which features were most predictive?]
  • Evaluation Metrics: [How did you measure performance (e.g., Accuracy, Precision, Recall, F1-score, ROC-AUC)? What were the results?]

7. Results & Interpretation

[Summarize the final results of your analysis. What do the findings mean in the context of the original problem statement? How would a business or stakeholder use this information?]

8. Conclusion & Future Work

[Provide a final summary of the project and its impact. Suggest potential next steps or further research that could be done.]

  • Next Step 1: [e.g., Deploy the model into a production environment.]
  • Next Step 2: [e.g., Collect more data to improve model accuracy.]
